Answer 1

public class MyClass {
    public static void main(String[] args) {
        int i = 479;
        double d = 56.893;
        boolean b = true;

        Integer obji = Integer.valueOf(i);
        Double objd = Double.valueOf(d);
        Boolean objb = Boolean.valueOf(b);

        if (obji instanceof Integer) {
            System.out.println("Integer Object");
        }

        if (objd instanceof Double) {
            System.out.println("Double Object");
        }

        if (objb instanceof Boolean) {
            System.out.println("Boolean Object");
        }
    }
}
