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.
