Java Learning, counting the number of occurrences of the same type from a string

1. Count the occurrences of uppercase letters, small letters, and other types from the string "as345asdzf* ()) Sddswe"

String s= "as345asdzf* ()) Sddswe"; intL = 0,b=0,o=0;  for(intI=0;i<s.length (); i++){   Chart= S.charat (i);//charat return index value    if(t>= ' A ' &&t<= ' Z ') {//determine if the lowercase letterl++; }Else if(t>= ' A ' &&t<= ' Z ') {//determine if it is an uppercase letterb++; }Else{//determine if it is another typeo++; }} System.out.print (L+ "," +b+ "," +o); }

2. Write a method that outputs a string that specifies the number of occurrences of a string

String s= "Javaqweejavaiojavawejava"

String s= "Javaqweejavaiojavawejava";         int count=0;         int index=-1;        String tofind= "java";          while ((Index=s.indexof (tofind))!=-1) {            s=s.substring (index+tofind.length ());            Count+ +;        }        System.out.print (count);                    }
