Question 06:

 Why Scanner class is used? Use Scanner class to read student names 

in an array of size 10 and then display the names of those students 

which contains word “Rehman” in their names.??

Answer:

In Java, Scanner is a class in java.util package used for obtaining the input of the primitive types like int, double, etc. and strings. Using the Scanner class in Java is the easiest way to read input in a Java program, though not very efficient if you want an input method for scenarios where time is a constraint like in competitive programming.

Code:

// code by saqib ale import java.util.Scanner; class Main { public static void main(String[] args){ // create object of scanner Class Scanner sc = new Scanner(System.in); // create string array String[] studentArray = new String[10]; // get the 10 student names form the user System.out.println("Enter the name of 10 students"); for(int i= 0; i < 10 ; i++){ studentArray[i] = sc.nextLine(); } //display names System.out.println("\nThe output results \n\n"); for(int i= 0; i < 10 ; i++){ // use contains() method which return tru or false value if(studentArray[i].contains("Rehman")){ System.out.println(studentArray[i]); } } } }

Output:
