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;
}
