Function Overload - String Program - Java Programs

Design a class to overload a function check() as follows:

void check(String str, char ch) – to find and print the frequency of a character in a string.

Example:

Input:
str = “success”
ch = ‘s’
Output:
number of s present is = 3

void check(String s1) – to display only the vowels from string s1, after converting it to lowercase.

Example:

Input:
s1 = “computer”
Output:
o u e

Java


class Overload{
    public static void check(String str, char ch){
        int count = 0;
        for(int i = 0; i < str.length(); i++){
            if(ch == str.charAt(i))
                count++;
        }
        System.out.println("Frequency = " + count);
    }
    public static void check(String s1){
        s1 = s1.toLowerCase();
        for(int i = 0; i < s1.length(); i++){
            char ch = s1.charAt(i);
            switch(ch){
                case 'a':
                case 'e':
                case 'i':
                case 'o':
                case 'u':
                System.out.print(ch + "\t");
            }
        }
    }
}
