Number of Occurrences of characters in a string

AskBot

Count the number of characters in a string, i have one simple problem.iam not getting it right.
the problem is....
the user enters one string.our program has to read the string entered by
user and then display the no.of occurances of individual characters in that
string.

for example if user enters a sring "character" then the output should be in
ascending order like...
a 2
c 2
e 1
h 1
r 1
t 1

i found the solution:

Code:

class SampleTest
{
public static void main(String arg[])
{
String str="hhaahhhr";
char[] c=str.toCharArray();
int loopcount=0;
int count=0;

for(int i=0;i<c.length;i++)
{
//System.out.println(c[i]+" "+i);
boolean flag=true;
for(int k=0;k<i;k++){
if(c[i]==(str.charAt(k)))
flag=false;
}
if(flag){
for(int j=0;j<str.length();j++)
{
if(c[i]==str.charAt(j))
count=count+1;
}
System.out.println(c[i]+" "+" "+(count));
count=0;
loopcount++;
}
}
}
}
