usemember.java

一个J2SE的简单入门

public class UseMember{
	int i = 10;
	
	class InnerClass{
		int i = 100;
		
		public int getInt() {
			return i;	//这里返回的是内部类中定义的i
		}
		
		public int getOutterInt(){
			return UseMember.this.i;	//这里返回的是外部类中定义的i
		}
	}
	
	public InnerClass getInnerClass(){
		return new InnerClass();
	}
	
	public static void main(String[] args) {
		UseMember test = new UseMember();
		UseMember.InnerClass inner = test.getInnerClass();
		System.out.println("inner.getInt(): " + inner.getInt());
		System.out.println("inner.getOutterInt(): " + inner.getOutterInt());	
	}
