Java Break Statement

When a break statement is encountered inside a loop, the loop is immediately terminated and the program control resumes at the next statement following the loop.
The Java break statement is used to break loop or switch statement. It breaks the current flow of the program at specified condition. In case of inner loop, it breaks only inner loop.
We can use Java break statement in all types of loops such as for loop, while loop and do-while loop.

Syntax:

jump-statement;
        break;

Java Break Statement with Loop

Example:

//Java Program to demonstrate the use of break statement   
//inside the for loop. 
public class BreakExample {
    public static void main(String[] args) {
        //using for loop 
        for(int i=1;i<=10;i++){
            if(i==5){
                //breaking the loop 
                break;
            }
            System.out.println(i);
        }
    }
}

Output:



Java Break Statement with Inner Loop

It breaks inner loop only if you use break statement inside the inner loop.

Example:

//Java Program to illustrate the use of break statement    

//inside an inner loop   

public class BreakExample2 {

    public static void main(String[] args) {

        //outer loop   

        for(int i=1;i<=3;i++){

            //inner loop  

            for(int j=1;j<=3;j++){

                if(i==2&&j==2){

                    //using break statement inside the inner loop  

                    break;

                }

                System.out.println(i+" "+j);

            }

        }

    }

}

Output:


Java Break Statement with Labeled For Loop

We can use break statement with a label. This feature is introduced since JDK 1.5. So, we can break any loop in Java now whether it is outer loop or inner.

Example:

//Java Program to illustrate the use of continue statement  

//with label inside an inner loop to break outer loop  

public class BreakExample3 {

    public static void main(String[] args) {

        aa:

        for(int i=1;i<=3;i++){

            bb:

            for(int j=1;j<=3;j++){

                if(i==2&&j==2){

                    //using break statement with label  

                    break aa;

                }

                System.out.println(i+" "+j);

            }

        }

    }

}

Output:


Java Break Statement in while loop

Example:

//Java Program to demonstrate the use of break statement  

//inside the while loop.  

public class BreakWhileExample {

    public static void main(String[] args) {

        //while loop  

        int i=1;

        while(i<=10){

            if(i==5){

                //using break statement  

                i++;

                break;//it will break the loop  

            }

            System.out.println(i);

            i++;

        }

    }

} 

Output:


Java Break Statement in do-while loop

Example:

//Java Program to demonstrate the use of break statement  

//inside the Java do-while loop.  

public class BreakDoWhileExample {

    public static void main(String[] args) {

        //declaring variable  

        int i=1;

        //do-while loop  

        do{

            if(i==5){

                //using break statement  

                i++;

                break;//it will break the loop  

            }

            System.out.println(i);

            i++;

        }while(i<=10);

    }

}

Complete Java masterclass for beginners -10 (switch statement)

Java Switch Statement The Java  switch statement  executes one statement from multiple conditions. It is like  if-else-if  ladder statement. The switch statement works with byte, short, int, long, enum types, String and some wrapper types like Byte, Short, Int, and Long. Since Java 7, you can use  strings  in the switch statement. In other words, the switch statement tests the equality of a variable against multiple values. Points to Remember There can be  one or N number of case values  for a switch expression. The case value must be of switch expression type only. The case value must be  literal or constant . It doesn't allow  variables . The case values must be  unique . In case of duplicate value, it renders compile-time error. The Java switch expression must be of  byte, short, int, long (with its Wrapper type),  enums  and string . Each case statement can have a  break statement  which is...

Loops in Java In programming languages, loops are used to execute a set of instructions/functions repeatedly when some conditions become true. There are three types of loops in Java. for loop while loop do-while loop Java For Loop vs While Loop vs Do While Loop Java For Loop The Java  for loop  is used to iterate a part of the program several times. If the number of iteration is fixed, it is recommended to use for loop. There are three types of for loops in java. Simple For Loop For-each  or Enhanced For Loop Labeled For Loop Java Simple For Loop A simple for loop is the same as  C / C++ . We can initialize the  variable , check condition and increment/decrement value. It consists of four parts: Initialization : It is the initial condition which is executed once when the loop starts. Here, we can initialize the variable, or we can use an already initialized variable. It is an optional condition. Condition : It is the ...

Complete Java masterclass for beginners -06 (Unicode System)

Unicode System Unicode is a universal international standard character encoding that is capable of representing most of the world's written languages. Why java uses Unicode System? Before Unicode, there were many language standards: ASCII (American Standard Code for Information Interchange) for the United States. ISO 8859-1 for Western European Language. KOI-8 for Russian. GB18030 and BIG-5 for chinese, and so on. Problem This caused two problems: A particular code value corresponds to different letters in the various language standards. The encodings for languages with large character sets have variable length.Some common characters are encoded as single bytes, other require two or more byte. Solution To solve these problems, a new language standard was developed i.e. Unicode System . In unicode, character holds 2 byte, so java also uses 2 byte for characters. lowest value:\u0000 highest value:\uFFFF Next Topic:  Operators In java Happy Coding
