boolean method trouble

java

Solution

Firstly, your entire `isMatch` method would be better collapsed to:

public boolean isMatch() {
    return num == 10;
}

Secondly, your existing code really will work, unless you're changing the value of `num`. You should look at whatever diagnostics you're using to show the output as `false`... I suspect they're misleading you. Is it possible that you're printing out the value of the field called `isMatch` rather than calling the method? That would explain it. This is one reason why it's a bad idea to have a method with the same name as a field. Additionally, I'd recommend making your fields private.

Short but complete example showing both the working method call and the "failed" field access (working fine, but not doing what you want):

public class BooleanTest {
    private int num;
    private boolean isMatch;

    public BooleanTest() {
        num = 10;
    }

    public boolean isMatch() {
        return num == 10;
    }

    public static void main(String[] args) {
        BooleanTest test = new BooleanTest();
        System.out.println(test.isMatch()); // true
        System.out.println(test.isMatch); // false
    }
}

It's not clear why you've got the field at all, to be honest - I'd remove it.

Problem

Im trying to implement a method to return the boolean true or false. The method initializes the boolean isMatch to true or false based on the if and else statement. ``` public class BooleanTest { int num; boolean isMatch; public BooleanTest() { num = 10; } public boolean isMatch() { //variable is already initialize to 10 from constructor if (num == 10) isMatch = true; else isMatch = false; return isMatch; } public static void main(String[] arg) { BooleanTest s = new BooleanTest(); System.out.println(s.isMatch); } } ``` The outprint of isMatch should be true, but i get the output isMatch is false. Is my boolean method wrong and how can i fix it? Thank you for your help.
