Boolean Statement Not Working

Apr 14, 2015

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.

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;

If Statement Requires A Return Of Type Boolean

Dec 6, 2014

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?

Here is my code the whole program is working correctly but the Boolean equals and the has code and it is a requirement for the assignment. Why it is not working.

I know there are issues with the code I am new with java and was struggling so I have to clean my code up before I submit the assignment but for right now I have the out put the way I want it except the Boolean and hash code methods always output that the rectangles aren't equal even when I know they are and it outputs the not equal statement twice??

If Statement Not Working?

May 5, 2014

I'm having a problem where an if statement isn't working. In the Person class boolean olderThan ignores my if statement so it always returns false and I just don't get why that's happening.

import java.util.Calendar;
public class Person {
private String name;
private MyDate birthday;

Program Involving For Loop And If Statement Not Working

Oct 23, 2014

Alright so I'm trying to write a code that implements a for loop and if statements that displays any number from 100-200 if the number is divisible by either 5 or 6 in rows of ten numbers each row. If it is not divisible by that number then it should go back to the beginning of the loop until it reaches 200. My main problem is that it doesn't display anything. I don't get any errors or anything but every time I run the program it just displays nothing. Sample output is at the bottom of the code.
 
public class Exercise5_11 {
public static void main(String[] args) {
int count = 0;
int i = 100; 
//for (the numbers from 100 to 200)
for (i = 100; i>100 && i<200; i++){
 
[Code] ....

/*Output
100 102 105 108 110 114 115 125 126 130
132 135 138 140 144 145 155 156 160 162
165 168 170 174 175 185 186 190 192 195
198 200
*/

It is still wip of course so I was trying to just get it to display int i but it doesn't do anything and I'm not really sure why.

How To Turn If Statement Into A Case / Switch Statement

Jun 19, 2014

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

Boolean Cannot Be Converted To Int

Jun 11, 2014

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);

Boolean Return Missing

Sep 25, 2014

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.,

Converting Boolean Into String

Feb 15, 2014

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();

How To Change Value Of Boolean Within A Method

Dec 1, 2014

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

Oct 13, 2014

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. **/

import java.util.HashSet;
import java.util.Vector;
public class BooleanRetrievalModel implements DocSearch {

Airline Two Dimensional Boolean Array

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);

Boolean Array And Sorting Elements Within It

May 24, 2014

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]?
