问题描述

我正在使用Java进行一些编码,但它不起作用:

I am doing some coding in Java, but it doesn't work:

public class job
{
   private static int count = 0;
   private int jobID;
   private String name;
   private boolean isFilled;

   public Job(, String title, ){
      name = title;
      isFilled = false;
      jobID = ++count;
  }
}

我需要在新的时候自动增加Id条目已创建。

I need to auto-increment the Id when a new entry is created.

推荐答案

试试这个:

Try this:

public class Job {
  private static final AtomicInteger count = new AtomicInteger(0);
  private final int jobID;
  private final String name;

  private boolean isFilled;

  public Job(String title){
    name = title;
    isFilled = false;
    jobID = count.incrementAndGet();
}

这篇关于Java自动增量id的文章就介绍到这了,希望我们推荐的答案对大家有所帮助,也希望大家多多支持!
