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 vowels from string s1, after converting it to lower case.
Example:
Input:
s1 ="computer"
Output : o u e
Program:
public class RAnsariOverload1 { void check (String str , char ch ) { int count = 0; int len = str.length(); for (int i = 0; i < str.length(); i++) { char c = str.charAt(i); if (ch == c) { count++; } } System.out.println("Frequency of " + ch + " = " + count); } void check(String s1) { String s2 = s1.toLowerCase(); int len = s2.length(); System.out.println("Vowels:"); for (int i = 0; i < len; i++) { char ch = s2.charAt(i); if (ch == 'a' || ch == 'e' || ch == 'i' || ch == 'o' || ch == 'u') System.out.print(ch + " "); } } }
Output:
