Question

Hello! I have a Java homework question that I could really use some help with. I keep getting an error, but I don't know what is wrong with my code. Thanks so much in advance!

The problem is:

6.9: VowelAnalyst Design and implement an application that reads a string from the user, then determines and prints how many of each lowercase vowel (a, e, i, o, and u) appear in the entire string. Have a separate counter for each vowel. Also count and print the number of nonvowel characters. SPECIFICATION OF PROMPTS, LABELS AND OUTPUT: Your code should use the prompt "enter string: ". After the input is read, there are six lines of output, each starting with a different label: "a: ", "e: ", "i: ", "o: ", "u: ", "other: " in that order. After each label is the required count. For example: if "aardvark heebie jeebies" were read in, the output would be: a: 3 e: 6 i: 2 o: 0 u: 0 other: 12 SPECIFICATION OF NAMES: Your application class should be called VowelAnalyst.

My code is:

import java.util.Scanner;
public class VowelAnalyst
{
   public static void main(String[] args)
   {
       String str;
       char ch;
       int aCount;
       int eCount;
       int iCount;
       int oCount;
       int uCount;
       int otherCount;
       Scanner input=new Scanner(System.in);
       System.out.print("enter string: ");
       str=input.next();
       aCount=0;
       eCount=0;
       iCount=0;
       oCount=0;
       uCount=0;
       otherCount=0;
       for(int pos=0;pos<str.length();pos++)
       {
           ch=str.charAt(pos);
           if(ch=='a')
               aCount++;
           else if(ch=='e')
               eCount++;
               else if(ch=='i')
               iCount++;
               else if(ch=='o')
               oCount++;
               else if(ch=='u')
               uCount++;
               else if(ch!='a'&&ch!='e'&&ch!='i'&&ch!='o'&&ch!='u')
               otherCount++;
               }
       System.out.println("a: "+aCount);
       System.out.println("e: "+eCount);
       System.out.println("i: "+iCount);
       System.out.println("o: "+oCount);
       System.out.println("u: "+uCount);
       System.out.println("other: "+otherCount);
   }
}

The error is:

import java.util.Scanner;

{
String str;
char ch;

int eCount;
int iCount;
int oCount;

System.out.print("enter string: ");
str=input.nextLine();

else if(ch!='a'&&ch!='e'&&ch!='i'&&ch!='o'&&ch!='u')
otherCount++;
}
System.out.println("a: "+aCount);
System.out.println("e: "+eCount);
System.out.println("i: "+iCount);
System.out.println("o: "+oCount);
System.out.println("u: "+uCount);
System.out.println("other: "+otherCount);
}
}

NOTE:- Change str=input.nextLine(); because next() will only input the first word not the whole string, and nextLine() will input whole line.
