Answer:
// program in java.
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

The answer is true. The Undo command is set up on the toolbar. You can undo up to 40 edits in your plan by clicking on the Undo button. If you want to undo all of the revises made, simply quit (close your Internet browser window or start a new plan) without saving.
Answer:
import java.util.Scanner;
public class num2 {
public static void main(String[] args) {
Scanner in = new Scanner(System.in);
int count =0;
int total = 0;
System.out.println("Enter the numbers");
int num = in.nextInt();
while(num!=-1){
total = total+num;
count++;
System.out.println("Enter the next number");
num = in.nextInt();
}
//Compute the average
double average = (double) total/count;
//Outputs
System.out.println("Total count of numbers entered "+(count));
System.out.println("Sum of the numbers "+total);
System.out.printf("Average is %.2f ",average);
}
}
Explanation:
- Using java programming language
- Import scanner class to receive user input
- declare variables count and total and initialize to zero
- Prompt user to enter numbers
- Use a while statement with the condition while(num!=-1)
- Within the while body keep prompting user to enter a number, increase count and update total
- when -1 is entered the loop breaks and average is calculated
- Use printf() method to print average to 2 decimal places.
