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

1.	Design a class to overload a function check ( ) as follows : (i) 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(ii) void check(String si) – to display only vowels from string si, after converting it to lower case.Example:Input:s1 = “computer”Output:o u e

(i) class CharacterVowel

{

public void checkering str, char ch) {

int c = 0, code,i,s;

str = str.toLowerCase( );

int len = str.length( );

for (code = 97; code < 122; code+ +) {

c = 0;

for (i = 0; i < len; i+ +) {

ch = str.charAt(i);

s = (int) ch;

if(s = = code) c = c + 1;

}

ch = (char)code;

if(c ! = 0) System.out.println(“Frequency of “+ch+ “is” +c);

}

(ii) public void check(String si) { int i;

char ch=0, chr=0;

for(i=0;i<s1. length(); i+ +) {

ch = s1.charAt(i);

if(Character.isUpperCase(ch))

chr = Character.

toLo werCase(ch);

if((s1 .charAt(i)==’a’) 11 (s1 .charAt(i) = ‘u’) | j(s1 .charAt(i) = = ‘o’)| | (s1 .

charAt(i)==’i’)

11 (s1 .charAt(i) = = ‘e’))

System.out.println(s1 .charAt(i));

}
