In this tutorial, we will learn how to use for loop in Java with the help of examples. how many times you want to loop through a block of code, use the for loop.
Syntax:
for (statement 1; statement 2; statement 3) {
// code block to be executed
}
Example:
package javaapplication;
/**
*
* @author Rathorji
*/
public class JavaApplication {
/**
* @param args the command line arguments
*/
public static void main(String[] args) {
int n = 5;
// for loop
for (int i = 1; i <= n; ++i) {
System.out.println(i);
}
}
}
output:
run:
1 2 3 4 5 |
For-Each Loop
loop through elements in an array
Example:
package javaapplication;
/**
*
* @author Rathorji
*/
public class JavaApplication {
/**
* @param args the command line arguments
*/
public static void main(String[] args) {
String[] persons = {"Rakesh", "Rathorji", "John", "Doe"};
for (String i : persons) {
System.out.println(i);
}
}
}
