It will allow you to scan forward through any collection. If you remove elements from an array using a traditional looping structure, you will encounter anIndexOutofBoundsException. This is because the size of the array changes as you iterate through it and you may have set the size of the...
C2 may then assume that the variable will likely continue to not be null in future executions and optimize the code using that assumption. The profile shows that a loop usually iterates thousands of times. C2 may decide to unroll and/or vectorize the loop based on that information. The ...
