How to create a sub array from another array in Java?

Question

How to create a sub-array from another array? Is there a method that takes the indexes from the first array such as:

methodName(object array, int start, int end) 

I don't want to go over making loops and making my program suffer.

I keep getting error:

cannot find symbol method copyOfRange(int[],int,int)

This is my code:

import java.util.*;  public class testing  {     public static void main(String [] arg)      {            int[] src = new int[] {1, 2, 3, 4, 5};          int b1[] = Arrays.copyOfRange(src, 0, 2);     } } 

Answer 1

You can use

JDK > 1.5

Arrays.copyOfRange(Object[] src, int from, int to) 

Javadoc

JDK <= 1.5

System.arraycopy(Object[] src, int srcStartIndex, Object[] dest, int dstStartIndex, int lengthOfCopiedIndices);  

Javadoc

Answer 2

Arrays.copyOfRange(..) was added in Java 1.6. So perhaps you don't have the latest version. If it's not possible to upgrade, look at System.arraycopy(..)
