You need to loop through the string using the indexOf method to COMPARE to the character you are searching for. You can use the length method to determine how many times to iterate through the loop.
You will need an IF statement inside the loop to do the comparison.
Post the code you have completed and we will be happy to help you get it working.
Here is what I have, I am very new to programming and Java So I am not sure if I am heading in the right direction. I am just starting off by tring to check for "A's"
CODE
import java.util.StringTokenizer;
import java.util.Scanner;
public class Main
{
public static void main (String[] args)
{
String phrase;
String oneMore;
Scanner input = new Scanner(System.in);
do
{
System.out.println();
System.out.println();
System.out.println ("Enter a phrase please:");
phrase = input.nextLine();
int length = phrase.length();
int countA = 0;
int index = 0;
while (index < length) {
if (phrase.indexOf() == 'a' ) {
countA = countA + 1;
}
index = index + 1;
}
System.out.println ("Number of A's" + countA);
// System.out.println ("Number of B's" + countB);
// System.out.println ("Number of C's" + countC);
// System.out.println ("Number of D's" + countD);
// System.out.println ("Number of E's" + countE);
// System.out.println ("Number of F's" + countF);
// System.out.println ("Number of G's" + countG);
// System.out.println ("Number of H's" + countH);
// System.out.println ("Number of I's" + countI);
// System.out.println ("Number of J's" + countJ);
// System.out.println ("Number of K's" + countK);
// System.out.println ("Number of L's" + countL);
// System.out.println ("Number of M's" + countM);
// System.out.println ("Number of N's" + countN);
// System.out.println ("Number of O's" + countO);
// System.out.println ("Number of P's" + countP);
// System.out.println ("Number of Q's" + countQ);
// System.out.println ("Number of R's" + countR);
// System.out.println ("Number of S's" + countS);
// System.out.println ("Number of T's" + countT);
// System.out.println ("Number of U's" + countU);
// System.out.println ("Number of V's" + countV);
// System.out.println ("Number of W's" + countW);
// System.out.println ("Number of X's" + countX);
// System.out.println ("Number of Y's" + countY);
// System.out.println ("Number of Z's" + countZ);
System.out.println("Would you like to check another phrase?");
System.out.println("Enter y/n");
System.out.println();
oneMore = input.nextLine();
System.out.println();
}
while (oneMore.equalsIgnoreCase("y"));
}
}
PS I use netbeans and it for some reason it cant find the method index0f()
I am kinda frusterated.
