for(int i=0;i<s.length();i++)

String s1=""+i;

int count=1;

Answer / jishnu

Sorry I dont want to give a detailed answer here cos no one e is going to read the code.

You can use Map<Char,List<Integer>> counterMap

Iterate through the length of the string
for(int i=i; i<s.length();i++){
if(counterMap.get(s.getCharAt(i))==nul){
//First time
List<Integer> a= new ArrayList<Integer>();
a.add(i);
counterMap.put(s.getCharAt(i),a);
}else{
counterMap.get(s.getCharAt(i)).add(i);
}


//We can iterate through keySet or entrySet to show the result
}

Answer / meet parikh

Here you go,

public class Hello {
static String s = "";
static String word = "Hello World";
public static void main(String[] args){
for(int i=0; i<word.length();i++){
char tchar = word.charAt(i);
if(!checkCharContains(tchar)){
int count = 0;
StringBuilder sb = new StringBuilder();
for(int j=0;j<word.length();j++){
char ttchar = word.charAt(j);
if(ttchar == tchar){
count++;
sb.append(j).append(",");
}
}
sb.deleteCharAt(sb.length()-1);
s += tchar + " : " + sb.toString() + " & " +
count + " \n";
}
}
System.out.println(s);
}
public static boolean checkCharContains(char t){
boolean result = false;
for(int i=0;i<s.length();i++){
if(s.charAt(i) == t){
result = true;
}
}
return result;
}
}

Answer / noor

Little change in the code

add this for loop
for (int x = i - 1; x >= 0; x--)

instead of
for (int x = i - 1; x > 0; x--)

Answer / binoy

I would make it simple.

public void printHello()
{

String s="Hello Good Morning";
int i=0;
for (char c: s.toCharArray())
{
System.out.print
(""+c+":"+i+count(c,s)+"\t");
i++;
}

}

public int count(char c, String s)
{
int index=-1;
int count =0;
while((index=s.indexOf(c+""))!=-
1)
{
s=s.substring(index+1);
count++;
}
return count;
}
