Can I have 2 diferent Constructor names in a single class?

Question

class Test{
double x;
double y;
Test( double a, double b)
x=a;
y=b;
//Can i hv another constructor name with is not test but other name? //Example
exam(double c, double d)
x=c;
y=d;
}

Answer 1

If you want different behavior for essentially the "same" constructor signature, use an additional variable to differentiate the signatures. For example:
Test(double a, double b) { this(a, b, false); }
Test(double a, double b, boolean exam) {
    if (exam) {
        // exam behavior
    } else {
        // normal Test behavior
}
