我正在用 Java 编写一些代码，但它不起作用:
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;
}
}
我需要在创建新条目时自动递增 Id。
最佳答案
试试这个:
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();
}
关于Java 自动递增 id，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/24305830/
