跪求JAVA高手帮忙编一个程序！急急急，非常感谢呀~

public class Complex {
private int entry;//实部
private int visual;//虚部
public Complex() {
super();
}
public Complex(int en, int vi) {
super();
this.setEntry(en);
this.setVisual(vi);
}
public int getEntry() {
return entry;
}
public void setEntry(int entry) {
this.entry = entry;
}
public int getVisual() {
return visual;
}
public void setVisual(int visual) {
this.visual = visual;
}
//显示：
public void showComp(){
System.out.println(this.getEntry()+"+"+this.getVisual()+"i");
}
//加法：
public Complex addComp(Complex c1,Complex c2){
int e = c1.entry + c2.entry;
int v = c1.visual + c2.visual;
Complex c = new Complex(e,v);
return c;
}
//减法：
public Complex subComp(Complex c1,Complex c2){
int e = c1.entry - c2.entry;
int v = c1.visual - c2.visual;
Complex c = new Complex(e,v);
return c;
}
//乘法：
public Complex multiComp(Complex c1,Complex c2){
int e = c1.entry*c2.entry - c1.visual*c2.visual;
int v = c1.visual*c2.entry + c1.entry*c2.visual;
Complex c = new Complex(e,v);
return c;
}
//相同返回true,不同返回false
public boolean equalComp(Complex c1,Complex c2){
return c1.entry==c2.entry && c1.visual == c2.visual;
}
}

//测试类
public class Test {
public static void main(String [] args){
//验证默认构造初始化：实部是0，虚部也是0
Complex c = new Complex();
System.out.print("默认构造结果是：");
System.out.println(c.getEntry());
System.out.println(c.getVisual());
//加法：
Complex c1 = new Complex(3,7);
Complex c2 = new Complex(5,6);
Complex cj = new Complex();
cj = c.addComp(c1,c2);
System.out.print("加法结果是：");
cj.showComp();
//减法：
Complex c3 = new Complex();
Complex c4 = new Complex();
Complex cm = new Complex();
cm = c.subComp(c1,c2);
System.out.print("减法结果是：");
cm.showComp();
//乘法：
Complex c5 = new Complex();
Complex c6 = new Complex();
Complex cc = new Complex();
cc = c.multiComp(c1,c2);
System.out.print("乘法结果是：");
cc.showComp();
//相等比较：
Complex c7 = new Complex(3,-3);
Complex c8 = new Complex(3,4);
Complex c9 = new Complex(3,4);
boolean resuls1 = c.equalComp(c7,c8);
boolean resuls2 = c.equalComp(c8,c9);
System.out.print("比较结果是：");
System.out.print(resuls1?true:false);
System.out.print(resuls2?true:false);
}
}
