Java中的重载Varargs方法
具有可变长度参数(Varargs)的方法可以具有零个或多个参数。另外，如果需要，可以重载Varargs方法。
演示此过程的程序如下：
示例
public class Demo {
public static void Varargs(int... args) {
System.out.println("\nNumber of int arguments are: " + args.length);
System.out.println("The int argument values are: ");
for (int i : args)
System.out.println(i);
}
public static void Varargs(char... args) {
System.out.println("\nNumber of char arguments are: " + args.length);
System.out.println("The char argument values are: ");
for (char i : args)
System.out.println(i);
}
public static void Varargs(double... args) {
System.out.println("\nNumber of double arguments are: " + args.length);
System.out.println("The double argument values are: ");
for (double i : args)
System.out.println(i);
}
public static void main(String args[]) {
Varargs(4, 9, 1, 6, 3);
Varargs('A', 'B', 'C');
Varargs(5.9, 2.5);
}
}输出结果
Number of int arguments are: 5 The int argument values are: 4 9 1 6 3 Number of char arguments are: 3 The char argument values are: A B C Number of double arguments are: 2 The double argument values are: 5.9 2.5
