  1. Answer B:

    Compiler will select the most accurate parameter definition. It selected the “int” rather than the “Integer” because the supplied parameters are closer to “int” of “Integer”. As for the decimal point number, they are double instead of float, because there is not “f” post-fix.

  2. Answer is B

    public class Test {
    public static void doSum(Integer x, Integer y){
    System.out.println(“Integer sum is ” + (x + y));
    }

    public static void doSum(double x, double y){
    System.out.println(“double sum is ” + (x + y));
    }

    public static void doSum(float x, float y){
    System.out.println(“float sum is ” + (x + y));
    }

    public static void doSum(int x, int y){
    System.out.println(“int sum is ” + (x + y));
    }

    public static void main(String[] args) {
    doSum(10, 20);
    doSum(10.0, 20.0);
    }
    }
    //Result
    //int sum is 30
    //double sum is 30.0
