Give output of the following function definition and also write the mathematical operation they carry out:

void test4(String x, String y)
{
    if(x.compareTo(y) > 0)
        System.out.println(x);
    else
        System.out.println(y);
}

if "AMIT" and "AMAN" are passed to the function.

AMIT

Working

The first differing characters of "AMIT" and "AMAN" are 'I' and 'A', respectively. So output of "AMIT".compareTo("AMAN") will be ASCII Code of 'I' - ASCII Code of 'A' ⇒ 73 - 65 ⇒ 8. The if condition is true so string x which is "AMIT" gets printed as the output.
