This an example of Java string programs, In this java program, we have to read strings using 'StringReader' and 'Scanner' class.

Read string using StringReader class

import java.io.IOException;
import java.io.StringReader;

public class ReadString1 
{
	public static void main(String[] args) 
	{
	     String s = "Hello World";
         
	     // create a new StringReader
	     StringReader sr = new StringReader(s);
         try 
         {
	         // read the first five chars
	         for (int i = 0; i < 5; i++)
	         {
	            char c = (char) sr.read();
	            System.out.print(" " + c);
	         }
	         // close the stream
	         sr.close();
	     }
         catch (IOException ex) 
         {
	         ex.printStackTrace();
	     }
	}
}

Output

H e l l o

Read String using Scanner class

import java.util.Scanner;

public class ReadString
{
	 public static void main(String args[])
	 {
		 // initialize and declare here.
		 int id;
		 String name;
		 
		 // create scanner class object.
         Scanner scanner = new Scanner(System.in);
       
         // enter the detail.
         System.out.print("Enter Employeeid : ");
              id=(scanner.nextInt());
         System.out.print("Enter EmployeeName : ");
              name=(scanner.next());    
         System.out.print("Id : " +id+ "\nName : " +name);
     }
}

Output

Enter Employeeid : 101
Enter EmployeeName : Chandra Shekhar
Id : 101
Name : Chandra Shekhar
