编写应用程序，测试上面定义的类，使用类中定义的各个方法并将其结果输出。
public class Class1 {
public static void main(String[] args) {
//定义几个数
int x = 37,y = 42,maxValue,minValue;
System.out.println("变量数值...");
System.out.println(" x = " + x);
System.out.println(" y = " + y);
//加
System.out.println("加...");
System.out.println(" x + y = " + (x + y));
//减
System.out.println("减...");
System.out.println(" x - y = " + (x - y));
//乘
System.out.println("乘...");
System.out.println(" x * y = " + (x * y));
//除
System.out.println("除...");
System.out.println(" x / y = " + (x / y));
//从除法中求得余数
System.out.println("计算余数...");
System.out.println(" x % y = " + (x % y));
//最大值
System.out.println("最大值...");
System.out.println(maxValue=Math.max(x,y));
//最小值
System.out.println("最小值...");
System.out.println(minValue=Math.min(x,y));
}
}
帮我看看这个行不？
public class IntegerTest
{
int x;
int y;
public IntegerTest(int x,int y)
{
this.x=x;
this.y=y;
}
public int sum()
{
return this.x+this.y;
}
public int minus()
{
return this.x-this.y;
}
public int multiply()
{
return this.x*this.y;
}
public int chu()
{
return this.x/this.y;
}
public int mod()
{
return this.x%this.y;
}
public int max()
{
if(this.x>=this.y)
{
return this.x;
}
return this.y;
}
public int min()
{
if(this.x<=this.y)
{
return this.x;
}
return this.y;
}
public static void main(String args[])
{
IntegerTest i=new IntegerTest(2,3);
System.out.println("x+y="+i.sum()+"\nx-y="+i.minus()+"\nx*y="+i.multiply()+"\nx/y="+i.chu()+"\nx%y="+i.mod()+"\n最大数为："+i.max()+"\n最小数为："+i.min());
}
}
class A
{
int x;
int y;
public A(int x1,int y1)
{
x=x1;
y=y1;
}
public int add(x1,y1)
{
return x1+y1;
}
public int add()
{
return add(x,y);
}
//写了加法后,减,乘,除法类似
//不过在除法的时候最好判断一下被除数是否是0
public static void main(String[] args)
{
A a=new A(10,15);
System.out.println(add(18,19));
//以下类似....
}
}
