废话不多说，直接上代码

打印基数

public class PrintNumberOne implements Runnable {
    PrintUtil printUtil = PrintUtil.getPrintUtil();

    @Override
    public void run() {
        for (; printUtil.startNumber < printUtil.number; ) {
            try {
                if (printUtil.startNumber % 2 == 1) {
                    Thread.sleep(1000);
                    System.out.println("-------" + Thread.currentThread().getName() + "正在打印基数" + printUtil.startNumber + "------");
                    printUtil.startNumber++;
                }
            } catch (Exception e) {

            }
        }
        System.out.println(Thread.currentThread().getName() + "已将0到" + printUtil.number + "的基数打印完毕");
    }
}

打印偶数

public class PrintNumberTwo implements Runnable {
    PrintUtil printUtil = PrintUtil.getPrintUtil();

    @Override
    public void run() {
        for (; printUtil.startNumber < printUtil.number; ) {
            try {
                if (printUtil.startNumber % 2 == 0) {
                    Thread.sleep(1000);
                    System.out.println("*******" + Thread.currentThread().getName() + "正在打印偶数" + printUtil.startNumber + "******");
                    printUtil.startNumber++;
                }
            } catch (Exception e) {
            }
        }
        System.out.println(Thread.currentThread().getName() + "已将0到" + printUtil.number + "的偶数打印完毕");
    }
}

valite帮助类

public class PrintUtil {
    static PrintUtil printUtil = new PrintUtil();
    public volatile Integer startNumber = 0;
    public volatile Integer number = 100;

    private PrintUtil() {

    }

    public static PrintUtil getPrintUtil() {
        return printUtil;
    }
}

运行主类

public class Test {
    public static void main(String[] args) {
        try {
            Thread printTwo = new Thread(new PrintNumberTwo());
            printTwo.start();
            Thread printOne = new Thread(new PrintNumberOne());
            printOne.start();
        } catch (Exception e) {

        }
    }
}

欢迎各位大佬指正
