Question

Write Java code that does the following

Ask the user to enter a file name.

Ask the user for two integers as the lower bound and the upper bound.

Use a loop to write all the odd numbers between the lower bound and the upper bound (inclusive) to the file, and then close the file.

Use either while loop, do while loop, or for loop to complete the program.

PrintWriter class is used.

The file is closed before the program terminates.

Answer 1

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

class PrintWriterExample
{
public static void main(String args[])
{
try
{
PrintWriter w1=null;
Scanner sc=new Scanner(System.in);
String fileName;
int lowBound,uppBound;
System.out.println("Enter a file Name : ");

fileName=sc.next();
w1=new PrintWriter(new File(fileName));
System.out.println("Enter lower bound : ");
lowBound=sc.nextInt();
System.out.println("Enter upper bound : ");
uppBound=sc.nextInt();
System.out.print("Odd Numbers : ");
for(int i=lowBound;i<=uppBound;i++)
{
if(i%2!=0)
{
w1.write(i+"\t");
}
}
System.out.println("Successfully write all the odd numbers between the lower bound and the upper bound to the file");
w1.flush();
w1.close();
}
catch(Exception e1)
{
System.out.println("Exception is "+e1);
}
}
}
