Let’s learn continue statement in java.
Continue statement in java
Continue statement skips a particular iteration and moves to next iteration. Continue statement in java is used in many loop control structures.
Continue keyword can be used with the loops, namely, for loop and do while loop.
Syntax
continue;
continue in java example
import java.util.*; public class ContinueJavaExample { public static void main(String[] args) { for(int a = 1; a <= 10; a++) { if(a % 2 != 0) { continue; } System.out.println(a + " "); } } }
Output:
2
4
6
8
10
Continue in nested for loop java
In nested for loop if continue statement is encountered, it jumps to very next inner loop. Meanwhile to jump current iteration of outer loop label can be used.
In the below java program we can use continue statement to skip number 6 of all numbers from 1 to 10.
public class ContinueExample
{
public static void main(String[] args)
{
for(int a = 1; a <= 10; a++)
{
if(a == 6)
{
// continue statement
continue;
}
System.out.println(a);
}
}
}
Output:
1
2
3
4
5
7
8
9
10
Java continue in while loop
In the below while loop, numbers from 1 to 10 are printed except 4 using continue statement.
public class ContinueWhileDemo
{
public static void main(String[] args)
{
int a = 1;
while(a <= 10)
{
if(a == 4)
{
// continue statement
a++;
continue;
}
System.out.println(a);
a++;
}
}
}
Output:
1
2
3
5
6
7
8
9
10
Java continue in do while loop
Similar to above java program we can replace with do while loop. Here the java program.
public class ContinueDoWhile
{
public static void main(String[] args)
{
int a = 1;
do
{
if(a == 7)
{
// continue statement
a++;
continue;
}
System.out.println(a);
a++;
}while(a <= 10);
}
}
Output:
1
2
3
4
5
6
8
9
10
Java continue label example or java continue label
Java continue label skips current iteration of outer loop. Here’s the java continue label example.
public class ContinueLabelExample
{
public static void main(String[] args)
{
outer: for(int a = 0; a < 5; a++)
{
System.out.println("\n" + "a : " + a + "\n");
for(int b = 0; b < 6; b++)
{
if(b == 2)
{
continue outer;
}
System.out.println("b : " + b);
}
}
}
}
Output:
a : 0
b : 0
b : 1
a : 1
b : 0
b : 1
a : 2
b : 0
b : 1
a : 3
b : 0
b : 1
a : 4
b : 0
b : 1
break statement in java
If break statement is encountered in a loop, that loop will terminate and the control will shift to next statement of the same loop.
Syntax:
break;
Basically break statement is used to terminate case in switch case statement in java.
Let’s see an example on break statement in java.
public class BreakStatementExample
{
public static void main(String[] args)
{
int[] evenNumbers = {2, 4, 6, 8, 10, 12, 14};
for(int n : evenNumbers)
{
if(n == 8)
{
break;
}
System.out.print(n);
System.out.print("\n");
}
}
}
Output:
2
4
6
