There is a String value Eg:('12560') and I need to put it into an array by index wise.

Eg : Input:

String x = "12560";

Output:

String arr[] = {"1","2","5","6","0"};

Here's a one line answer:

JAVA 8 and above:

x.split("");

JAVA 7 and below:

x.split("(?!^)");

Didn't read the original post before answering it.. Also the OP may just see the first upvoted answer from the post and use it without reading the comments and not use the simplified form that java 8 provides. So this answer actually adds something. :P – Rohan Agarwal Mar 29 '20 at 19:28

This should do the job:

String x = "12560"
char[] chars = x.toCharArray();

They want a String array – Hagai Wild Mar 29 '20 at 18:47
That is a `char[]` but OP seems to ask for `String[]`. – Zabuzard Mar 29 '20 at 18:47

Not really clear, the requirement seems to be " i need to put it into an array by index wise." – TacheDeChoco Mar 29 '20 at 18:50

Something like this shall work.

Create a new String [] array, proceed with adding each character as a new string inside it.

     String x = "12560";

      String output [] = new String[x.length()];
      for(int i = 0 ; i < x.length() ; i++){
          output[i] = x.charAt(i)+"";
          System.out.println(output[i]);
      }

Output -

This code is worked for me.

    //c is the user input value
    String c  = "12560";
    //create a String array to add final results
    String finArr[] = new String[c.split("").length];
    //put input value to an array by splitting
    String arr[] = c.split("");
    //add
    for(int i=0;i<arr.length;i++){
        finArr[i] = arr[i];
    }
    for(int j=0;j<finArr.length;j++){
        System.out.println(finArr[j]);
    }

The "add-loop" is completely uncessary. The data is already in `arr`. Also, you are executing the split twice, once to get the length, once to get the data. But one execution is enough. Additionally, you should not go for a c-style array notation `Foo foo[]` but for Java-like `Foo[] foo` notation. – Zabuzard Mar 29 '20 at 18:49
