[求助]初学一个小程序有错 请指教

package lang;
import java.io.*;

public class Woker {
public static void main(String[] args) {
int Num=000001;
int Wage=0;;
int NewWage=100;
Woker woker;
System.out.println("Num"+Woker.getNum()+"Wage:"+woker.getWage()+"NewWage:"+woker.getNewWage();)
}
class woker{
private int num;
private int wage;
private int newwage;
public void setNum(int num)
{this.num=num;}
public void setWage(int wage)
{this.wage=wage;}
public void setNewWage(int newwage)
{newwage=wage+100;}
public int getNum()
{return this.num;}
public int getWage()
{return this.wage;}
public int getNewWage()
{return newwage;}
}
初学 ,不太会改错误 请指教啊

package lang;
public class Worker
{
public static void main(String[] args)
{

worker no1=new worker();
int Num=1;
int Wage=0;
int NewWage=100;
no1.setNum(Num);
no1.setWage(Wage);
no1.setNewWage(NewWage);
System.out.println("Num"+no1.getNum()+"Wage:"+no1.getWage()+"NewWage:"+no1.getNewWage());
}
class worker
{
private int num;
private int wage;
private int newwage;

public void setNum(int num)
{this.num=num;}
public void setWage(int wage)
{this.wage=wage;}
public void setNewWage(int newwage)
{newwage=wage+100;}
public int getNum()
{return this.num;}
public int getWage()
{return this.wage;}
public int getNewWage()
{return newwage;}
}
}
怎么还不行啊 郁闷

不知道你是不是这个意思？？！！

楼主你把worker类写到测试类里了

----------------解决方案--------------------------------------------------------

在main函数里要先new一下worker，然后再调用类里的方法，调用的时候要注意所调用的方法的返回值类型，后面是否有参数，这些在调用时要一一对应才行啊！楼上的斑竹所写的
worker no1=new worker();
int Num=1;
int Wage=0;
int NewWage=100;
no1.setNum(Num);
no1.setWage(Wage);
no1.setNewWage(NewWage);
就是这个意思！

主类不能子类重名哈哈不知道对不对
