首先，编写一个类ChongZai，该类中有3个重载的方法void print()；其次，

再编写一个主类来测试ChongZai类的功能。

public class Chongzai1 {
//	首先，编写一个类ChongZai，该类中有3个重载的方法void print()；其次，

	int a,b,c;
	
	
	public int getA() {
		return a;
	}
	public void setA(int a) {
		this.a = a;
	}
	public int getB() {
		return b;
	}
	public void setB(int b) {
		this.b = b;
	}
	public int getC() {
		return c;

	public void setC(int c) {
		this.c = c;

	public double add (double a,double b)
	
	{
		return(a+b);
	}
	public double add (double a,double b,double c)

	public double ji(double a,double b)

	}
	
	
	
	public static void main(String [] args)
	   {
		   Chongzai1 c=new Chongzai1();
		 
		   System.out.println(c.add( 3, 4));
