如下代码:<br> //MethodOverload.java
//Using overloaded methods
package HJssss;
public class zhuce {
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:
1 2 3 |
The square of integer 7 is 49
The square of double 7.5 is 56.25

上述代码展示了Java的方法重载特性。
满足以下条件的两个或多个方法构成“重载”关系:
1.方法名相同。
2.参数类型不同,参数个数不同,或者是参数类型的顺序不同。
注意:返回值不能作为方法重载的条件。
