运行下列程序，分析super关键字的使用，以及父类与子类之间的隐藏和重写关系

class superClass{

　　 int x

　　superClass( ){

　　　　 x = 3

　　　　System.out.println("in superClass : x = "+x)

　　 }

　　void doSomething( ){

　　　　System.out.println("in superClass.doSomething( )")

　　}

class subClass extends superClass{

　　 int x



　　subClass( ){

　　　　super( ) //call constructor of superClass

　　　　x = 5

　　　　System.out.println("in subClass : x = "+x)

　　}

　　void doSomething( ){

　　　　super.doSomething( ) //call method of superClass

　　　　System.out.println("in subClass.doSomething( )")

//call x of superClass

　　　　System.out.println("super.x = "+super.x+" sub.x = "+x) 　　

　　}

}

public class inheritance{

　　public static void main( String args[ ] ){

　　　　subClass subC = new subClass( )

　　　　subC.doSomething( )

　　}

}

-Run the following procedure to use the super keyword analysis, as well as the parent class and subclass relationship between the hidden and rewriting class superClass {int x　superClass () {x = 3　System.out.println (" in superClass: x = " +x) } void doSomething () {System.out.println ("　in superClass.doSomething () " ) }} class subClass extends superClass {int x　subClass () {super () // call constructor of superClass x = 5　System.out.println (" in subClass: x =" +x) } void doSomething () {super.doSomething () // call method of superClass System.out.println (" in subClass.doSomething () " ) // call x of superClass System.out.println ("　super.x = " +super.x+"　sub.x = " +x) }} public class inheritance {public static void main (String args [] ) {subClass subC = new subClass ()　subC.doSomething () }}
