Answer 1

Dear Student ,

As per the requirement submitted above , kindly find the below solution.

Question 1 :

Here a new java with name "main.java" is created, which contains following code.

main.java :

/*Java program to find numbers between 13-93 that ends with 3*/
//Class Main
public class Main
{
//main method
   public static void main(String[] args) {
   //declaring variable
   int i;
   for (i=13;i<=93;i++)
   {
   //checking if number is end with 3
   if(Integer.toString(i).endsWith("3")){
   //display number
       System.out.print(i+" ");
   }
   }
   }
}

======================================================

Output : Compile and Run main.java to get the screen as shown below

Screen 1 :main.java

Question 2 :

main.c :

/*Write a for loop to display a string entered by the user backwards.*/
import java.util.*;
//Class Main
public class Main
{
//main method
   public static void main(String[] args) {
   //creating object of scanner class
   Scanner scanner=new Scanner(System.in);
   //asking user to enter string
   System.out.println("Enter a string : ");
   //reading string
   String inputString=scanner.nextLine();
   //converting string to character array
   char[] strChar = inputString.toCharArray();
   //finding length of string
   int strLength=strChar.length;
   //using for loop to print string backwords
   for(int i=strLength-1;i>=0;i--)
   {
   //display string in backwords
   System.out.print(strChar[i]);
   }
   }
}
================================

Output :Compile and run above program to get the screen as shown below

Screen 1:Screen asking to enter string

Screen 2 :Screen showing string backwords
