methodoverloadingtest.java

几个简单的java学习代码

  class MethodOverloading{

	void receive( int i ){
		System.out.println("Receive one int data ");
		System.out.println("i = "+i);
	}

	void receive( int x, int y ){
		System.out.println("Receive two int datas ");
		System.out.println("x = "+x+" y = "+y);
	}

	void receive( double d ){
		System.out.println("Receive one double data ");
		System.out.println("d = "+d);
	}

	void receive( String s ){
		System.out.println("Receive a string ");
		System.out.println("s = "+s);
	}

  }

　

  public class MethodOverloadingTest{
	public static void main( String args[ ] ){
	
		MethodOverloading mo = new MethodOverloading( );

		mo.receive( 1 );
		mo.receive( 2, 3 );
		mo.receive( 12.56 );
		mo.receive( "very interesting, isn't it?" );
	}

 }

　

 运行结果为：

 C:\>java MethodOverloadingTest 

 Receive one int data 

 i = 1

 Receive two int datas 

 x = 2 y = 3

 Receive one double data 

 d = 12.56

 Receive a string 

 s = very interesting, isn't it?
