import java.util.*;

// class definition

class Main

{

// main method of the class

public static void main (String[] args) throws java.lang.Exception

{

try{

// object to read input

Scanner scr=new Scanner(System.in);

System.out.print("Enter the String:");

// read string from user

String str=scr.nextLine();

System.out.print("Enter the character:");

// read character

char ch=scr.next().charAt(0);

// variable to count the occurrence of character

int char_count=0;

for(int i=0;i<str.length();i++)

{

// find the character i string

if(ch==str.charAt(i))

// increase the count

char_count++;

}

// print the count

System.out.println("count of "+ch+" in the String is:"+char_count);

}catch(Exception ex){

return;}

}

Explanation:

Read a string from user and assign it to variable "str".Then read a character to and assign it to variable "ch".Then Declare a variable "char_count" to count the occurrence of character in the string.Find the count of character in the string. Here upper case character is different than lower case.

Output:

Enter the String:Monday

Enter the character:n

count of n in the String is:1

Enter the String:Nobody

Enter the character:n

count of n in the String is:0

What is Python in programming?

Python is a interpreted, high-level programming, object-oriented, language with a dynamic semantics. Its high-level built-in data structures, combined with dynamic typing and dynamic binding, make it very appealing for Rapid Application Development, as well as for use as a scripting or glue language to connect existing components together.

Python's simple, easy-to-learn syntax emphasizes readability, lowering the cost of program maintenance. Python also supports modules as well as packages, which promotes program's modularity and reuse of code. The Python interpreter and extensive standard library are freely distributable and available in source or binary form for all major platforms.
