java命令运行java文件找不到main()方法

[从入门到不放弃]

class Person{
private int age;
private String name;
public void setName(String Name){
this.name=Name;
}
public void setAge(int Age){
this.age=Age;
}
public String getName(){
return name;
}
public int getAge(){
return age;
}
public String getInfo(){
return "Name: '"+name+"\n"+"Age: "+age;
}
}
class Student extends Person{
private String school;
public String getSchool(){
return school;
}
public void setSchool(String School){
this.school=School;
}

public String getInfo(){
return "Name: '"+getName()+"\n"+"Age: "+getAge()+"\n"+"School: "+school;
}
}
public class TestOverwrite{
public static void main(String[] args){
Student student=new Student();
Person person=new Person();
person.setName("none");
person.setAge(1000);
student.setName("Jhon");
student.setAge(18);
student.setSchool("AHUT");
System.out.println(person.getInfo());
System.out.println(student.getInfo());
}
文件名与类名一致，但是java命令运行时找不到main方法

求大佬帮忙解释一下，，小白挣扎的很痛苦

你还没编译呢，先编译在运行 E:\新建文件夹>javac TestOverwrite.java E:\新建文件夹>java TestOverwrite Name: 'none Age: 1000 Name: 'Jhon Age: 18 School: AHUT

[咸哼酒家]

用eclipse或ide来跑程序吧

先编译成.class文件，然后再运行，建议你先找本JAVA书看一下

[遇见1995]

没有编译.
具体看二楼.
通常都是
javac +类名.java 编译成字节码,即类名.class文件

java 类名 运行程序,这里是在jvm(java虚拟机)中运行字节码文件.
