动手动脑
方法重载
程序代码
package teacher;
public class MethodOverload {
public static void main(String[] args)
{
System.out.println("The square of integer 7 is " + square(7));
System.out.println("\nThe square of double 7.5 is " + square(7.5));
}
public static int square(int x)
{
return x * x;
}
public static double square(double y)
{
return y * y;
}
}
运行结果
The square of integer 7 is 49
The square of double 7.5 is 56.25
结果分析
应为进行了方法重载,所以当传入不同的参数时得到不同的答案。
