Java code

public class VarArgsTest {    public static void main(String[] args) {        m1();        m1("one");        m1("one","two");        //m1("one","two","three");//报错，因为系统不知道调用哪个方法...            }        public static void m1(String s1,String s2){        System.out.println("m1(String s1,String s2)");    }    public static void m1(){        System.out.println("m1()");    }    public static void m1(String s){        System.out.println("m1(String s)");    }    public static void m1(String s,String... str){        System.out.println("m1(String s1,String... str)");    }    public static void m1(String... str){        System.out.println("m1(String... str)");    }}
