From source file:Main.java

public static void main(String[] args) {
    Short sObj = new Short("10");

    byte b = sObj.byteValue();
    System.out.println(b);//w w  w .j a  v a 2  s . co  m

    short s = sObj.shortValue();
    System.out.println(s);

    int i = sObj.intValue();
    System.out.println(i);

    float f = sObj.floatValue();
    System.out.println(f);

    double d = sObj.doubleValue();
    System.out.println(d);

    long l = sObj.longValue();
