java 可变参数的实质

public class kebiancanshu {
//这里演示了，可变参数的实质是可变数组；
public static void print(String  ...name){
for(String temp: name )
System.out.print(temp + "  ");

System.out.println();
System.out.println(name.length);
System.out.println();

}
public static void main(String[] args) {
String name0 = "hello";
String name1 = "word";
String name2 = "ge";
kebiancanshu.print(name0);
kebiancanshu.print(name0,name1);
kebiancanshu.print(name0,name1,name2);

}

}

运行的结果：

hello  
1


hello  word  
2


hello  word  ge  
3
