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
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 + " ");
}
}
}
First understand the algorithm carefully. Then study the program line-by-line and compare it with the output. Finally, review the explanation section to strengthen your logic and programming understanding.
Rewrite the program without looking at the code. Modify values, conditions or logic and run it again. This helps improve confidence and strengthens coding skills much faster.
