In below I have uploaded the “count repeated characters in string using java”.text files. So this is the choice you can download this letter count text files implement this coding as it is.

Some of the important aspect I have used to count number of characters in a string java. Such as:-

  • Import java.util.*== For taking input;
  • Arrays== To store input;
  • Char ==To partition each word;
  • Initializing the inputs;

Now check the coding one by one line and make understating on it to count occurrences of each character in string java.

1| import java.util.*;
2|
3| public class convert
4| {
5| public static void main(String[] args)
6| {
7| System.out.println(“Enter Here ……………”);
8| Scanner input=new Scanner(System.in);
9| String value=input.next();
10|
11| //Count length………………………….
12| int count=String.valueOf(value).length();
13|
14| //Loop for separate………………………
15| char ini=’0′;
16| char inside[]=new char[count];
17| for (int i=0; i<count; i++)
18| {
19| ini=String.valueOf(value).charAt(i);
20| inside[i]=ini;
21| }
22|
23| //Array to convert into number……………
24| int arr[]=new int[count];
25| for (int i=0; i<count; i++)
26| {
27| arr[i]=inside[i];
28| }
29|
30| //Counting the char…………………
31| int count1=0;
32| int arr3[]=new int[count];
33| for (int i=0; i<arr.length; i++)
34| {
35| for(int j=0; j<arr.length; j++)
36| {
37| if (arr[i]==arr[j])
38| {
39| count1++;
40| }
41| }
42| arr3[i]=count1;
43| count1=0;
44| }
45| for (int i=0; i<arr.length-1; i++)
46| {
47| if (inside[i]!=inside[i+1])
48| {
49| System.out.println(inside[i]+” = “+arr3[i]);
50| }
51| }
52| }
53| }
