JAVA培训用实用代码

				public class A{
					private int s = 111;
					
					public class B {
						private int s = 222;
						
						public void mb(int s) {
							System.out.println(s); 	  // 局部变量s
							System.out.println(this.s); // 内部类对象的属性s
							System.out.println(A.this.s); //  外层类对象属性s
						}
					}
					public static void main(String args[]){
						A a = new A();
						A.B b = a.new B();
						b.mb(333);
