初学小白求助此java代码如何敲，不是做题思路，是直接可以在控制台上运行的代码，最好附带敲好的代码

package Project1;

public class ChuQi {

public static void main(String[] args){
Scanner input=new Scanner(System.in);

String[] Name=new String [5];
Name[0]="蝴蝶效应";

int DVDcun=2;
boolean[] shu=new boolean[Name.length];
int[] date=new int[Name.length];
int[] ciShu=new int[Name.length];
for(int i=0;i shu[i]=true;
date[i]=0;
ciShu[i]=0;
}
int num;
int[] xuHao={1,2,3,4,5,6};
do{
System.out.println("************店面管理系统************");

System.out.println("\t4.借出DVD");
System.out.println("\t5.归还DVD");
System.out.println("\t6.退出");
System.out.print("请选择:");

}
}
while(num==2){
