I want to run it 500 times how do i do it ?
我想运行它 500 次，我该怎么做？
Thank You
谢谢

With Java 8 Streams you could do it like that
使用 Java 8 Streams 你可以这样做
IntStream.range(0, 500).forEach(i -> System.out.println("Hello World!"));

You would use a for loop.
您将使用 for 循环。
for(int i = 0; i < 500; i++)
//the code you would like to loop here

Try like this :
像这样尝试：
class ForDemo {
public static void main(String[] args){
for(int i=0; i<500; i++){
System.out.println("Hello world");
}
}
}

for(int x=0;x<500;x++){
System.out.println("Hello World!");
}
You should really read about control structures. This is programming 101
您应该真正阅读有关控制结构的信息。这是编程101

Try this
试试这个
public static void main(String[] args){
for(int j=0; j<500; j++){
System.out.println("Hello world");
}

I googled this because I think it is more expressive if one can say:
我在谷歌上搜索了这个，因为我认为如果有人可以说：
Integer.times(500).execute(i -> System.out.println("Hello world"))
We should really not bother with indexes in such a case. I think the question is legit.
在这种情况下，我们真的不应该打扰索引。我认为这个问题是合法的。
groovy, for example, has incorporated this in the language:
例如，groovy 已将其纳入语言：
500.times {
println "Hello world"
}
Would be nice to have this addition to Java as well. And of course you can currently use the IntStream approach, as explained in previous comments.
将这个添加到 Java 中也会很好。当然，您目前可以使用 IntStream 方法，如之前的评论中所述。
