I guess, you'll have to do manual iterating over every single character in the String and then finally form your final String...

Welcome to the Ranch

You will have to write down on paper what you intend to do; then you can covert it to code.

import java.util.*;

class  StrCount {
  public static void main(String[] args) throws Exception{
    String st ="aabbc";
  
    char[]third =st.toCharArray();
    for(int counter =0;counter<third.length;counter++){
      char ch= third[counter];
      int count=0;
      for ( int i=0; i<third.length; i++){
        if (ch==third[i])
          count++;
      }
      boolean flag=false;
      for(int j=counter-1;j>=0;j--){
        if(ch==third[j])
          flag=true;
      }
      if(!flag){
        System.out.println("Character :"+ch+" occurs "+count+" times ");
      }
    }
  }
}

successfully executed....
any other way please inform me

You aren't supposed to print "a appears 4 times". You are supposed to have a String with 4a at the beginning.

Please UseCodeTags next time. I've added them for you this time. And also add some indentation; another thing I've added.
