The default value is 1 if the last allocated object was an instance, and 3 if it was an array. The following example shows how to set the number of loaded cache lines to 5: -XX:AllocatePrefetchLines=5 Only the Java HotSpot Server VM supports this option. -XX:AllocatePrefetchStepSize=...
Do you mean you want to iterate (loop - like with a for, while or do-while) over the array, printing out the index and the value in the array at that index? *There are some methods on certain classes that can do fancy things in memory with native code...but I don't think we...
There are several ways to print an array in Java. Here are a few options: Using a loop: int[] array = {1, 2, 3, 4, 5}; for (int i = 0; i < array.length; i++) { System.out.print(array[i] + " "); } Using the Arrays.toString() method: import java.util.Arrays; ...
