1.两个线程交替打印1-100
2.三个线程交替打印1-100
3.子线程循环3次，接着主线程循环5次，再子线程循环3次，主线程循环5次，如此反复，循环3次
4.两个线程，一个线程打印1~ 52，另一个线程打印A~Z，打印顺序是12A34B…5152Z
5.写10个线程，第一个线程从1加到10，第二个线程从11加20…第十个线程从91加到100，最后再把10个线程结果相加
6.三个窗口同时卖票

}5.写10个线程，第一个线程从1加到10，第二个线程从11加20…第十个线程从91加到100，最后再把10个线程结果相加
package com.example.practice.Thread;class Job implements Runnable {private int count = 1;int sum = 0;@Overridepublic void run() {synchronized (this) {for (int i = count; i < count + 10; i++) {sum += i;}count += 10;}}
