banana dresser grammar potato revive uneven assess

Write a program that gets a word from the keyboard and determines whether it has this property. treat uppercase and lowercase letters alike. That means that poTato also has this property.

2. Write a program that generates a random number (between 1 and 10 inclusive) 100 times. Output the total number of 1s, 2s, ….10s.

Code language is Java. using JGrasp to code

Answer 1

1.

Code:

import java.util.*;  // library file that contains string functions
import java.io.*;  // library file that contains input/output stream reader/writer

// defining class
class main {
        public static void main (String[] args) {
                
                Scanner sc = new Scanner(System.in);
                String word = sc.nextLine();  // taking input
                String word1 = word.substring(0);  // extracting a substring of the word leaving out first letter
                word1 =  word1 + word.charAt(word.length()-1); // adding the extracted substring with 1st letter
                if(word1.equalsIgnoreCase(word)){  // checking condition
                    System.out.println("Yes");
                }else{
                    System.out.println("No");
                }
        }
}
  
        

Output:

2.

Code:

import java.util.*;
import java.io.*;

class main {
        public static void main (String[] args) {
                
                // define the range 
        int max = 10; 
        int min = 1; 
        int range = max - min + 1; 
        int[] arr = new int[11];
  
        // generate random numbers within 1 to 10 
        for (int i = 0; i < 100; i++) { 
            int rand = (int)(Math.random() * range) + min; 
            arr[rand]++;
        }
        for(int i=1; i<11; i++){
            System.out.println("Number of "+i+"'s: "+arr[i]);
        }
        }
}

Output:
