求一个简单的用java语言编写的文件管理器的源代码🙏

Answer 1

public class complie {
int i,j;
public complie(int i,int j)//构建一个复数类
{
this.i=i;
this.j=j;
}
complie add(complie c)//复数加法
{
int l,k;
l=c.i+i;
k=c.j+j;
return (new complie(l,k));
}
complie cut(complie c)//复数减法
{
int l,k;
l=i-c.i;
k=j-c.j;
return (new complie(l,k));
}
void ToString()//将复数输出
{
System.out.println("复数为："+i+"+"+j+"i");
}

public static void main(String[] args)
{
complie a=new complie(4,5);
complie b=new complie(2,3);
System.out.println("构造的复数类为：");
a.ToString();
b.ToString();
System.out.println("运算复数a+b=：");
a.add(b).ToString();
System.out.println("运算复数a-b=：");
a.cut(b).ToString();

}
}
