This article is to share with you about how to achieve the for cycle in Java, the editor thinks it is very practical, so I share it with you to learn. I hope you can get something after reading this article.

The first way to write:

Public class Solution {public static void main (String [] args) {for (int j = 0; j < 3; jacks +) {System.out.println (j);}

The result of the output is:

012

The second way is:

Public class Solution {public static void main (String [] args) {for (int j = 0; j < 3; + j) {System.out.println (j);}

The result of the output is:

012

Both output are the same, please note

If you write it this way, is it all right?

Public class Solution {public static void main (String [] args) {int j = 0; for (; j < 3; + j) {System.out.println (j);}

The result is the same.

012

Summary:

For both the for loop and the if operation, the default value of x is calculated first, rather than the value within the expression.

The above is how to achieve the for cycle in Java. The editor believes that there are some knowledge points that we may see or use in our daily work. I hope you can learn more from this article. For more details, please follow the industry information channel.
