Question

Use the arraycopy method to copy 10 elements from the front of an array x to the front of an array y.

Answer 1

To copy 10 elements from the front of array x to the front of array y, use the System.arraycopy method in Java with the source and destination arrays, starting positions set to 0, and the number of elements to copy set as 10.

Step-by-step explanation:

The arraycopy method in Java is used to copy a specified number of elements from one array to another. The task at hand requires copying 10 elements from the front of an array x to the front of an array y. Here's a step-by-step explanation of how this can be accomplished:

1. Ensure both arrays, x and y, are declared with the appropriate size, and x has at least 10 elements.
2. Call the System.arraycopy method with the following parameters:
   

The actual Java code snippet to accomplish this would look something like this:

System.arraycopy(x, 0, y, 0, 10);

After this operation, the first 10 elements of array x will be copied into the first 10 positions of array y.
