Here is my code:
public class Exercixe09_04 {
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
System.out.println("Enter a string: ");
String s1 = input.next();
System.out.println("Enter a character: ");
String s2 = input.next();
char c = s2.charAt(0);
int num = count(s1, c);
System.out.print(num);
}
public static int count(String str, char a)
{
int count = 0;
for(int i =0; i < str.length(); i++)
if(str.charAt(i) == 'a'){
count++;
}
return count;
}
}
When I compile and run it, nothing prints. Can someone please help me figure out what is wrong?
import java.util.Scanner;
public class Exercixe09_04 {
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
System.out.print("Enter a string: ");
String s1 = input.next();
System.out.print("Enter a character: ");
String s2 = input.next();
char c = s2.charAt(0);
int num = count(s1, c);
System.out.println(num);
}
public static int count(String str, char a) {
int count = 0;
for (int i = 0; i < str.length(); i++)
if (str.charAt(i) == a) {
count++;
}
return count;
}
}
Sample run:
falsetru@jmlee12:/tmp$ java Exercixe09_04
Enter a string: Hello
Enter a character: l
