How to stop printing null in an array
提问by Ibyc
How do I stop my program from printing out the positions of the array that are null, when I'm going through an array and printing the positions out?
当我遍历数组并打印出位置时，如何阻止我的程序打印出空数组的位置？
for(int i=0;i<array.length;i++)
{
System.out.print(array[i]);
}
It's simple like this, but how do I stop it from printing out the positions that are null? Thanks in advance for an answer to this simple question...
就像这样简单，但是如何阻止它打印出空的位置？提前感谢您对这个简单问题的回答...

for(int i=0;i<array.length;i++)
{
if (array[i]!=null) {
System.out.println(array[i]);
}
}

You just use the i of the for loop to check inside the array what the value is. I hope this is what you needed.
您只需使用 for 循环的 i 来检查数组内部的值是什么。我希望这是你所需要的。
for (int i = 0; i < array.length; i++)
{
if(array[i] != null)
{
System.out.print(array[i]);
}
}
