How to convert Array to List in Java

Sometime you need to convert an array variable to List or Collection for some iterative (looping) process. Actually Java come with a handy function to achieve this – Arrays.asList. See example below :

import java.util.Arrays;
import java.util.List;
public class ArrayToList {
  public static void main(String[] argv) {
	  String sArray[] = new String []{"Array 1", "Array 2", "Array 3"};
	  //convert array to list
	  List lList = Arrays.asList(sArray);

    This is not true to all, you can’t convert byte array to list nor do char [], javadoc speaks out.So, the topic is not perfectly correct.

      It must be Object[] not primitive{int,float,long,double,char} type array.
