Learn how to use the Java for loop to iterate over arrays and collections efficiently. Discover syntax, examples, and best practices for optimizing your code.
For example, we can rewrite the previous example as below. We have taken out thecounterinitialization before the loop. We have moved the counter increment and the termination statements inside the loop body. The statements are the same as the previous version. int[]array=newint[]{0,1,2,3,...
