You have 2 errors in the code, both due to index starting from 1 instead
than from 0.
* for(int i = 1; i<arr.length;i++){//here i couldnt print out the name in
args[0]*
* System.out.println(arr[i]+ " ");*
you cannot print arr[0] if i start from 1 . On the first loop it will print
arr[1] and in the last loop it will print arr[5] that is not existing.
Change this in
for(*int i = 0*; i<arr.length;i++){//here i couldnt print out the name in
args[0]
System.out.println(arr[i]+ " ");
Same issue here
*public static void generateNewName(String[] arr){*
* String name1 = arr[1];*
if you start from arr[1] you will never get arr[0].
change it with
public static void generateNewName(String[] arr){
String name1 =* arr[0];*
and it should work.
