1,随机数组创建
import java.util.Random;
Random ran =new Random();
int a=ran.nextInt(2);
2 ,控制循环时间间隔
while(!result) {
Thread.sleep(5 * 100); //设置暂停的时间 5 秒
count++;
if (count == 15) {
result = true;
break;
}
} catch (InterruptedException e) {
e.printStackTrace();
}
}
3,判定字符串是否相等
String s1 = new String("abc");
String s2 = new String("abc");
boolean result = s1.equals(s2);
System.out.println("The result is :" + result);
