Can we initialise final variable using constructor

Question

validation of final keyword

Answer 1

Yes, once final member is set it cannot be changed though.

class Test {
private final int NUM;

Test(int num) {
this.NUM = num;
}

public int getNum() {
return NUM;
}
}

public class Program
{
public static void main(String[] args) {
Test t = new Test(5);
System.out.println(t.getNum());
}
}
