extend1.java

这一些程序都是实验之用

public class Base  {
	
	public int publicVarOfBase=1;
	private int privateVarOfBase=1;
	int defaultVarOfBase=1;
	
	protected void methodofBase(){}
	}
 class Sub extends Base{
		 public void methodOfSub(){
		 	publicVarOfBas=2;
		 	defaultVarOfBase=2;
		 	privateVarOfBase=2;
		 	methodOfBase();
		 							 }
		 							 
		 public static void main(String argv[]) {
		 	 Sub sub=new Sub();
		 	 sub.publicVarOfBase=3;
		 	 sub.prativeVarOfBase=3;
		 	 sub.defaultVarOfBase=3;
		 	 
		 	 sub.methodofBase();
		 	 sub.methodofBase();
		 	 
		 }							 
		 
		 
		 
		 
		 
	}
