Double constructors, with and without array

[Juukamen]

here is the code i got:

class test {
	private final String abc;
	private final int x;
	private final int[] y;
	private final int[] z;

	public test(String abc, int x){
		this.abc = abc;
		this.x = x;
	}


	public test(String abc, int x, int[] z, int[] y) {
		this.abc = abc;
		this.x = x;
		this.z = z;
		this.y = y;
	}
}

and the error message

test.java:41: error: variable y might not have been initialized
	}
	^
1 error

Tool completed with exit code 1

what is wrong with the code and how should it look like ?

The error message tells you exactly what is wrong: variable y might not be initialised. The error occurs on line 41 which you have not posted.

the rest is commented away so that is the whole code. removed all of the comments and still;

class test {
	private final String abc;
	private final int x;
	private final int[] y;
	private final int[] z;

	public test(String abc, int x){
		this.abc = abc;
		this.x = x;
	}


	public test(String abc, int x, int[] z, int[] y) {
		this.abc = abc;
		this.x = x;
		this.z = z;
		this.y = y;
	}
}

test.java:10: error: variable y might not have been initialized
	}
	^
1 error

Tool completed with exit code 1

if you look at line 10, y is not there, it's one "}" bracket. and the variables at use there is abc, x. not y.

You have declared your variables as final. This means that you can never change the value of those variables. At the end of the first constructor what value will y (and z) have?

[Juukamen]

shait, removed final and all worked perfectly. got tons of things to learn still.

[Junky]

removed final

Is that the correct solution? Maybe y and z should be final? If they are then you need to assign them default values in the first constructor.
