Cannot Convert Int To Boolean

Dec 11, 2014

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.

Cannot Convert From String To Boolean And Int To String

Apr 6, 2014

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] ......

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);

Odd And Even Numbers With Boolean?

Apr 14, 2014

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;

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.,

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.

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

Airline Two Dimensional Boolean Array

Feb 23, 2015

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]?

Single Linked List Boolean

Feb 13, 2015

i'm currently studying over single linkedLists and i'm just writing various methods for it. One method i'm currently stuck on is writing a remove method where it returns a boolean true if its found and it will delete it, and false if the target isn't found. My problem is that it always comes up as flase and i know that the target is in the linked list. Here is the code for my method.

Java Code: public boolean remove(E item){
Node<E> ptr = head;
while(ptr!= null && !item.equals(item))
ptr = ptr.next;
if(ptr.data.equals(item)){
ptr.next = ptr.next.next;

Passing A Boolean Parameter From One Method To Other

Jan 30, 2015

Java SE Runtime Environment build 1.8.0..This is part of the code:

public static int addAddress (String[] number, boolean[] front, double[] total) {
int num = 0;
double ffee = 0;
/*boolean value = false;*/
 
[code]...

I have tried using the line of code commented out, /*boolean value = false;*/. However, another error is displayed. The compiler shows the following...

Inspection.java:33: error: incompatible types: boolean cannot be converted to boolean[]
front[num]= defineFront(num, value);
^
Note: Some messages have been simplified; recompile with -Xdiags:verbose to get full output error...I know that boolean values are by default stored as false, once you create the array. However, I'm having trouble passing the variable to the method.

Creating A Conditional Boolean Variable

Nov 26, 2014

I am new to java and this seems like it has to be really simple, but so far I am unsuccessful. I want to create a boolean value if a certain condition is met. I need my application to compare who is logged in to my web app with the value for who created a particular report.

I retrieve the creator of a report in report.getCreatedBy() and I can display the current user with user.getName(). I need my application to determine if the person logged in is the same as the createdBy value and then set isAuthor() = true

if (user.getName().equals(report.getCreatedBy())) {
isAuthor = true;
}
else isAuthor = false;

Then I want to user the isAuthor true or false to display certain information in my jsp. That part I can handle, just not sure what I am missing / have incorrect from above.

class MusicalInstrument {
public String name;
public boolean isPlaying;
public boolean isTuned;
public MusicalInstrument(){
isPlaying = false;
isTuned = false;
