Using String And Boolean In If Statement?
May 24, 2015
I want to write a program that ask if you want to go to the movies. If the user type in yes then it'll print out (Alright let go) but if the user type no then it would print (whatever). The trouble that I'm having is. What's the best way to use Boolean and Strings together in a if statement?
public class Night {
static Scanner UserInput = new Scanner (System.in);
public static void main (String [] args){
boolean user1, user2;
user1 = true;
user2 = false;
[Code] ....

code=Java
import java.util.Random;
import java.util.Scanner;
public final class Derp {
public static int WIN, Tick;
public static Scanner Input = new Scanner(System.in);
[code]...
why this boolean statement isn't working correctly. It's not detecting that the WIN and Tick are the same and instead chooses to always run the second statement.

I wrote a class for encapsulating coins and I was to do a boolean statement but when I test the statement the results are not showing.Here is the code for my coin class coins.java
package project_3;
/**
*
* @author user a
*/
public class Coins {
private double pennies;
private double nickles ;
private double dimes ;
private double quarters ;
private int dollars ;

Im trying to do this
if( 2/2 ) {
system.out.println( "number is not event" );
} else {
system.out.println( "number is event" );
}
However if statement requires a return of type boolean. So im forced to this instead
if( (2/2) != 0 ) {
system.out.println( "number is not event" );
} else {
system.out.println( "number is event" );
}
Is there a way to achieve the former method, without typecasting, if you had to typecast how do you do it?

I have errors in the "if" and both "else if" ... The compiler says "cannot convert from String to boolean and int to String ...
instructions:
1. Add two private instance variables, String courseName and char grade to this class.
2. Add accessor and mutator methods for these instance variables.
3. Add a method register which receives an integer data type and returns String data type according to the argument passed to it ("Math" for 1, "English" for 2, "No course" for any other input)
What I have so far:
package assignment9;
public class BannerUser
{
private int userId;
public int getUserId()
{
return this.userId;
}
public void setUserId(int userId)
[Code] ......

I have this project due and its asking that i print out what type of triangle it is when the user inputs 3 sides. I have most of it done and working, but it pops up different windows instead of using one window for everything. The assignment says it needs all the final info to be in one window. The boolean is coming from another method. I'm unsure how to get it into a string (Or if that's what i have to do). The method must return a boolean true/false.
import javax.swing.*;
public class Triangle {
public static void main(String[] args) {
int side1 = getSides();
int side2 = getSides();
int side3 = getSides();

Is it possible to use a if-else statement for string variables?
I am trying to make a program that execute different depending on the user typing in "male" or not when he/she gets asked about gender. The program execute the else part no matter what the user types in.
Here is my code :
import java.util.Scanner;
public class c4Testname {
public static void main(String[]args){
Scanner input = new Scanner(System.in);
System.out.println("Type in your gender");

import java.io.IOException;
import java.util.*;
public class Guesser {
public static void main(String[] args) throws IOException {
char[] alphabet = "abcdefghijklmnopqrstuvwxyz1234567890 .,:;'-".toCharArray();
[Code] .....
I'm writing a program which will take a three letter word (for now) and then try to guess the word over and over again until it finds it, then print the word and the amount of tries it took to find it.
The problem: at the moment the program will find the word but not break out of the for loop when it does. I think it doesn't like the char to String conversion somewhere along the line.

I have some spatial datasets which are availabe in a opensource metadata catalog software GeoNetwork and in a PostGIS database.The problem is that the student who created the database used different IDs for the same datasets. So the IDs in the GeoNetwork differs from the IDs in the postGIS database. They only have the same name So, if someone uploads a new dataset into GeoNetwork, the same dataset is uploaded into a postGis database too.
Now I want to add a ID column into the database to give the field the same ID like the ID in geonetwork. I think I can only do this with using the filename cause they are same in both cases.Now I want to alter the table in eclipse with following code:
PHP Code:
Connection con = null;
Statement stmt = null;
String query = null;
String filen = filename.substring(0, filename.indexOf('.'));
con = DriverManager.getConnection("jdbc:postgresql_postGIS://localhost:5433" + "user=postgres;password=dominik1;" + "database=geonetwork"); --> (the connection data will later be in a properties file)
query = "ALTER TABLE " + filen + " ADD GN_id INTEGER(10) ";
stmt = con.createStatement();
stmt.execute(query); mh_sh_highlight_all('php');
But i get the following findbug error:
Failed to execute goal org.codehaus.mojo:findbugs-maven-plugin:2.5.2:check (default) on project services: failed with 1 bug
org.fao.geonet.services.resources.UploadAndProcess .exec(Element, ServiceContext) passes a nonconstant String to an execute method on an SQL statement ["org.fao.geonet.services.resources.UploadAndProces s"] At UploadAndProcess.java:[lines 83-299]..
I tried to suppress this error and worked with PreparedStatement and String.Format but I can't get rid of this error.

So from what iv learnt in Java and programming in general is that using a case statement is far more efficient that using multiple IF statements. I have an multiple IF statements contained within a method of my program, and would like to instead use a case statement.
public String checkPasswordStrength(String passw) {
int strengthCount=0;
String strengthWord = "";
String[] partialRegexChecks = { ".*[a-z]+.*", // lower
".*[A-Z]+.*", // upper
".*[d]+.*", // digits
".*[@#$%!]+.*" // symbols

So I want to make a simple Java that ask the user to pick a powers and it has two options.If the user picks magic then execute the first if statement then ask the user again which type of magic the user wants.I can't make it work it keeps printing the else statement. Why is that?
import java.util.Scanner;
public class Variable {
static Scanner zcan = new Scanner(System.in);

I do not see a boolean trying to be converted into an int. Could my decompiler have caused this?
this.redStones[this.tabIDHover == i].drawSprite(6 + paddingX + ((client.clientSize >= 1) ? 2 : 0) - ((this.longTabs && client.clientSize >= 1) ? 240 : 0) + x, 261 + paddingY + ((this.longTabs && client.clientSize >= 1) ? 37 : 0) - ((client.clientSize == 0) ? 261 : 0));
this.redStones[this.tabIDHover == i + 8].drawSprite(6 + paddingX + ((client.clientSize >= 1) ? 2 : 0) + x, 298 + paddingY);

I am making a program which accepts two user inputs one being a letter either upper or lower case and the other being a number. the out come should be some thing like this:
G
GG
GGG
GGGG
GGGGG
This is assuming the user inputted 'G' and '5'.
here is the code i have so far:
package week10;
import java.util.Scanner;
public class integer {
public static void main(String args[]) {
Scanner user_input = new Scanner( System.in );
[Code] ....
The problem i am having is that i cant get the number that is inputted to be accepted as a variable to be used for the program.

how to determine if an integer is even or odd by using a boolean method. I think I have the method right, but it's calling the method into the main that has got me stumped.
import java.util.Scanner;
public class Odd_Even {
public static void main(String[] args) {
//Scanner, variables
Scanner input = new Scanner(System.in);
int number;

So I'm trying to check if the new coordinates vs original coordinates are diagonal and 1 line further, and if there is a piece there(getNum()) if it's 2 lines further, so I'm trying to return a boolean value then.
so if it's the first if, it returns true, if it's the 2nd it returns true, then I say else for all other scenario's, and return false there, but my compiler says my method is missing a return statement.
public boolean check(int[] d) {
int x,y;
x = loc[0][0];
y = loc[0][1];
int sx = d[0];
int sy = d[1];
[Code] .....
Edit: used a local boolean and returned that after my if's.,

I read in a book that when you change the value of a method parameter that's a boolean or other basic datatype within the method it only is changed within the method and remains the same outside. I want to know if there is some way for me to actually change it within the method. For example:
public class Change {
void convert(boolean x, boolean y, boolean z) { //i want to set x,y, and z to false in this
x = false;
y = false;
z = false;
[code]...
I want to put in part1, part2, and part3 when i call the method than i want them to be set to false within the method. The specific reason i asked this question was because im trying to code a battleship and i have a subroutine class with a method that when its called it checks if a ship has been sunk. If the there was a sink than the method will set a ton of boolean variables to false.
Just to clarify, I want something like this:
void convert(thing1,thing2,thing3,thing4) {
//some code here that sets thing1,thing2,thing3, and thing4 to false
}
// than in main:
boolean test1 = true;
boolean test2 = true;

Boolean retrieval model using skiplist. I don't know how to code it. I have modified it but I'm not sure it work out. What are the modifications I can made.
/**My requirement is to implement two methods for Boolean Retrieval:
● index(String dir)
○ index()supposed to go over all files under "dir". There will be no subdirectories inside it.
● retrieve()
○ retrieve() supposed to return name of all the documents under "dir" that satisfies the given query. Note that, only basename of the files are to be returned, not the full path.
○ Query can be of two forms:
■ OR: returned doc should contain at least one term from the query.
■ AND: returned doc should contain all the terms from the query. **/

I have a boolean array that looks like this
boolean seat[][] = new boolean[2][3];
I reserved one row for first class and another for economy class. This code works just as I want but my question is how can I loop through it so I don't need all the if statements? I tried it many ways. I tried something like this but I cant get it to work.
for (int row=0;row<seat.length;row++{
for (int col=0;col<seat[row].length;col++){
if (seat[0][col]==false){
seat[0][col]=true;
System.out.println("You have number 0" + row + in first class);

If I have a boolean array that contains 30 elements (boolean[] fish), how do I go about isolating every 10 elements to use for something specific?
Say there are 30 types of fish stored within the boolean array and 0-9 are fish found specifically in the Indian Ocean, 10-19 are fish found specifically in the Atlantic, and 20-29 are fish specifically found in the Pacific Ocean. And for those 10 fish [0-9], [10-19], [20-29], each is a different color (red, orange, green, blue, white, black, silver, yellow, purple and gold), where the colors and locations of the fish are enum types Colors and Locations.
How do I go about appointing those characteristics to the fish?
Ex: elements [0-9] are fish from the Indian Ocean and [0] is red, [1] is orange, [2] is green, [3] is blue, [4] is white, [5] is black, [6] is silver, [7] is yellow, [8] is purple, and [9] is gold.
elements [10-19] are fish from the Atlantic Ocean and [10] is red, [11] is orange, [12] is green, [13] is blue, [14] is white, [15] is black, [16] is silver, [17] is yellow, [18] is purple, and [19] is gold.
elements [20-29] are fish from the Indian Ocean and [20] is red, [21] is orange, [22] is green, [23] is blue, [24] is white, [25] is black, [26] is silver, [27] is yellow, [28] is purple, and [29] is gold.
Will I need to appoint those characteristics in the constructor after initializing fish = new boolean[30]?

Create an abstract class called Student. The Student class includes a name and a Boolean value representing full-time status. Include an abstract method to determine the tuition, with full-time students paying a flat fee of $2,000 and part-time students paying $200 per credit hour. Create two subclasses called FullTime and PartTime. Create an application that demonstrates how to create objects of both subclasses."
