JAVA实现任意两个数的加减乘除

class Complex
{
	private double real = 1.0;
	private double imag = 2.0;
	
	public void add()
	{
		double sum =real+imag; 
		System.out.println("sum=" + sum);
	}
	
	
	public void subtraction()
	{
		double diffence =real-imag; 
		System.out.println("diffence=" + diffence);
	}
	
	public void multiplication()
	{
		double product =real*imag; 
		System.out.println("product=" + product);
	}
	
	public void division()
	{
		double consult =real/imag; 
		System.out.println("consult=" + consult);
	}
	
	public Complex()
	{
		real = imag=0.0;
	}
	
	public Complex(double real,double imag)
	
	{
		this.real = real;
		this.imag = imag;
	}
	
	
}
	

public class zuoyezhong 
{
	
	public static void main(String[] args) 
	{
	
		Complex c = new Complex(1.5,2.5);
				
		c.add();
		c.subtraction();
		c.multiplication();
		c.division();
	}	
	
}
