一简单线程同步笔试题分享,欢迎纠错分享更多思路

public class WorkSum {
  static volatile int step=1;
  static volatile boolean run=true;
  public static void main(String[] args){
    new Thread(()-> work("work1",(Integer a)-> a%2!=0)).start();
    new Thread(()-> work("work2",(Integer a)-> a%2==0)).start();
  }
  static void work(String name, Function<Integer,Boolean> checker){
    int sum=0;
    while(run&&sum<99){
      if(checker.apply(step)){
        System.out.println(name + " add "+ sum + "+" + step +"="+(sum+step));
        sum+=step;
        if(sum>=99){
          run=false;
          System.out.println(name + " get Sum"+ sum);
