public class Myclass4 {
public static void main(String[] args) {
String str="welcome to school";
StringBuffer s=new StringBuffer(str);

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

int count=1;

for(int j=i+1;j<s.length();j++){

if(s.charAt(i)==s.charAt(j)){

count++;

s.deleteCharAt(j);

}

}

System.out.println(s.charAt(i)+" appears "+count);
}
}
}
