Unconditional control statement

 Jump statements or unconditional control statement:

• Unconditional control statement is also called a jump statement.
• There are three kinds of jumping statements,

*Break

*Continue

Break statement:

• The break statement is used to execute particular blocks only.
• For example, the switch case.

Syntax:

1. Loop or if conditions

   break;

   or

   lable_name: Loop or if conditions

   break lable_name;

Example program:

1. package exampleprogram;

   import java.util.Scanner;

   public class Break_Example {

       public static void main(String[] args) {

           int[] num = {1000, 2000, 3000, 4000};

           boolean found = false;

           Scanner input = new Scanner(System.in);

           go:

           for (int i = 1; i <= 3; i++) {

               System.out.println("Enter your PIN number : ");

               int pin = input.nextInt();

               for (int n : num) {

                   if (n == pin) {

                       found = true;

                       break;

                   } 

               }

               if (found) {

                   System.out.println("Entered PIN number is correct.");

                   System.out.println("You can choose the below options \n1.Cash withdrawal \n2.Cash deposit \n3.Mini Statement");

                   break;

               } else {

                   System.out.println("Sorry try again!!!");

                   System.out.println("You let with " + (3 - i) + " more options...");

                   System.out.println("Entered PIN number " + pin + " is incorrect.\nPlease re-enter the pin number");

               }

           }

       }

   }

Output:

Continue statement:

• Continue statement is used inside loops.
• Whenever a continue statement is encountered inside a loop, control directly jumps to the beginning of the loop for the next iteration, skipping the execution of statements inside the loop’s body for the current iteration.

Syntax:

1. Loop or if conditions

   continue;

   or

   lable_name: Loop or if conditions

   continue lable_name;

Example program:

1. package exampleprogram;

   import java.util.Scanner;

   public class Continue_Example {

       public static void main(String args[]) {

           Scanner read = new Scanner(System.in);

           reading:

           for (int i = 1; i <= 3; i++) {

               System.out.print("Enter a even number: ");

               int value = read.nextInt();

               verify:

               if (value % 2 == 0) {

                   System.out.println("You are enterd even number : "+value);

                   break reading;

               } else {

                   System.out.println("Please enter even number only.");

                   System.out.println("You can enter " + (3 - i) + " times only...");

                   continue reading;

               }

           }

       }

   }
