public class Test {
public static void main (String a[]){
String s ="UNDERSTAND";
char rep[] = new char [s.length()];
StringBuffer rept=new StringBuffer();
boolean flag=false;
for(int i=0;i<s.length();i++){
int k=0;
for(int j=0;j<rept.length();j++){
if( s.charAt(i) == rept.charAt(j))
flag=true;
}
if(flag==false){
rept = rept.append(s.charAt(i));
}
}
System.out.println("Rept = "+rept);
for(int i=0;i<rept.length();i++){
char var= rept.charAt(i);
int counter=1;
for(int j=s.indexOf(var);j<s.lastIndexOf
(var);j++){
if(var == s.charAt(j)){
counter++;
}
}
System.out.println( " "+var+ " : "+counter);
}
}//main
}//Test

import java.util.Vector;
class test
{
public static void main(String []dasf)
{
String s="Manikandan,GTEC,vellore" ;
int count,a,c;
for(int i=0;i<s.length();i++)
{
count=0;c=0;a=0;
for(int j=0;j<s.length();j++) //counting
{
if(s.charAt(i)==(s.charAt(j)))
{
count++;
}
} while(a<=i)// checking duplicate
{
if(s.charAt(i)==s.charAt(a))
{
c++;
}
a++;
}
if(c==1)
System.out.println(s.charAt(i)+" = "+count);
}
}
}
o/p:
M-1
a-3
n-3
i-1
k-1
d-1
,-2
G-1
T-1
E-1
C-1
v-1
e-2
l-2
o-1
r-1
i done it for case sensitive.
In the checking Duplicate code "c" will increment more than
one if duplicate presents.
if any doubt in above code contact me at

Answer / dilip
Actually what i think is take integers from a-z and
initialize each with 0
then take the string & using charAt & equalsIgnoreCase
increment the respaective values & then print the same.....

int counter = 1;

Answer / kanthi
well, one way of doing this is to take up a counter
variable initialised to 0. Then, there will be 2 for loops.
First one starts at 0 and the second one starts at 1+(the
upper loop variable) and both iterate for a
UNDERSTAND.length() . In the loop, u can start by comparing
each char in the string with every other char using charAt
() method. If a match is found then increment the counter
variable. At the end of the inner loop, u will have the
number of times a particular character is repeated. Just
print the result out. That way, counter variable can be
reused for the next character again.
Code might be something like this:
int counter = 0;
for(int i=0;i<str.length();i++){
for(int j=i+1;j<str.length();j++)
{
if(charAt(i).equals(charAt(j))
counter++;
}
System.out.println(charAt(i) + '-' + counter);
}
Hope this works.. please tell me if u find any mistake with
the logic.
