方法的重载

方法的重载：1)方法名相同，参数个数不同
                 2)方法名相同，参数类型不同
                 3)方法名相同，参数顺序不同

class student
{
String stuID;
String stuName;
String stuSex;
student()
{
stuID="s01";
stuName="张三";
stuSex="男";
}
student (String ID )
{
stuID=ID;
}
student (String ID,String Name ,String Sex)
{
stuID=ID;
stuName=Name;
stuSex=Sex;
}
}
public class studentTest
{
public static void main(String [] args)
{
student stu1=new student();
student stu2=new student("s03");
student stu3=new student("s09","王二","男");
System.out.println("stu1.stuID="+stu1.stuID+"stu1.stuName="+stu1.stuName+"stu1.stuSex="+stu1.stuSex);
System.out.println("stu2.stuID="+stu2.stuID+"stu2.stuName="+stu2.stuName+"stu2.stuSex="+stu2.stuSex);
System.out.println("stu3.stuID="+stu3.stuID+"stu3.stuName="+stu3.stuName+"stu3.stuSex="+stu3.stuSex);
}
}
