java 编写一个可对复数进行加减运算的程序
1、real和image这两个field前面的static去掉。
2、public Complex() 这个构造器去掉，如果要接受输入的话，应该放到main方法里，这样这个类更清晰。
3、静态方法Complex_add和Complex_minus没指定返回值类型，应该返回的是Complex。另外方法名字首字母应小写。
4、参考这个：

java:创建复数类并实现复数的基本运算

}

}
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;
}
@Override
public String toString() {
return "(" + a + "+" + b + "i)";
}
}
package main;
public class ComplexTest {
public static Complex add(Complex c1, Complex c2) {
return new Complex(c1.getA() + c2.getA(), c1.getB() + c2.getB());

用JAVA实现复数的混合运算的源程序
public class Complex
{
private double realPart;
private double imaginaryPart;
public Complex(double a, double b)
{
this.realPart = a;
this.imaginaryPart = b;
}
public Complex add(Complex a)
{
Complex result = new Complex(this.realPart + a.realPart, this.imaginaryPart + a.imaginaryPart);//(why?)
return result;
}
public Complex decrease(Complex a)
{
Complex result = new Complex(this.realPart - a.realPart, this.imaginaryPart - a.imaginaryPart);//(why?)
return result;
}
public Complex multiply(Complex a)
{
double newReal = this.realPart*a.realPart - this.imaginaryPart * a.imaginaryPart;
double newImaginary = this.realPart*a.imaginaryPart + this.imaginaryPart * a.realPart;
Complex result = new Complex(newReal, newImaginary);
return result;
}
public Complex divide(Complex a)
{
Complex conjugate = new Complex(this.realPart, -this.imaginaryPart);
Complex multiplication = conjugate.multiply(a);
multiplication.realPart /= this.realPart*this.realPart + this.imaginaryPart * this.imaginaryPart;
multiplication.imaginaryPart /= this.realPart*this.realPart + this.imaginaryPart * this.imaginaryPart;
return multiplication;
}
public String toString()
{
String show = this.realPart + " + " + this.imaginaryPart + "i";
return show;
}
public static void main(String [] args)
{
Complex a = new Complex (2, 3);
Complex b = new Complex (1,1);
System.out.println((a.add(b)).toString());
System.out.println((a.decrease(b)).toString());
System.out.println((a.multiply(b)).toString());
System.out.println((a.divide(b)).toString());
}
}
java 中实现复数的加减
（1）：具体代码(附注释)
复数类：
public class Complex {
private float shibu;
private float xubu;
Complex()
{this(0,0);
}
Complex(float shibu,float xubu){
this.shibu=shibu;
this.xubu=xubu;
}
public void Add(Complex p)
{
Complex result=new Complex();
result.shibu=this.shibu+p.shibu;
result.xubu=this.xubu+p.xubu;
System.out.print("加法结果为:"+result.shibu+"+"+result.xubu+"i");
}
public void Sub(Complex p)
{
Complex result=new Complex();
result.shibu=this.shibu-p.shibu;
result.xubu=this.xubu-p.xubu;
System.out.print("加法结果为:"+result.shibu+"+"+result.xubu+"i");
}
public void Mul(Complex p)
{
Complex result=new Complex();
result.shibu=this.shibu*p.shibu-this.xubu*p.xubu;
result.xubu=this.shibu*p.xubu+p.shibu*this.xubu;
System.out.print("乘法结果为:"+result.shibu+"+"+result.xubu+"i");
}
public static void main(String[] args) {
Complex fushu1=new Complex(1,2);
Complex fushu2=new Complex(3,4);
fushu1.Add(fushu2);
fushu1.Sub(fushu2);
fushu1.Mul(fushu2);
}
}
