symbol : method deleteCharAt(int,int,int)
location: class java.lang.StringBuilder
stringBuilder.deleteCharAt(8, 11, 14);

1 error




import java.util.Scanner;

public class Java {

//Main Method
public static void main(String[] args)throws Exception {

java.io.File file = new java.io.File("Welcome.txt");
Scanner input = new Scanner(file);

//Create a Scanner
String s = input.nextLine();
System.out.println( s );

//Invoke the countLetters method to count each letter
int[] counts = countLetters(s.toLowerCase());
for (int i=0; i < counts.length; i++) {
if (counts[i] != 0)
System.out.println((char)('a' + i) + " appears " + counts[i] + ((counts[i] == 1) ?
" time" : " times"));
}
}

//Count each letter in the string
public static int[] countLetters (String s) {

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

}
return counts;
}
