Java for loop
// Starting on 0:
for(int i = 0; i < 5; i++) {
System.out.println(i + 1);
}
// Starting on 1:
for(int i = 1; i <= 5; i++) {
System.out.println(i);
}
// Both for loops will iterate 5 times,
// printing the numbers 1 - 5.

// Example of a for loop in java that will iterate the number of times entered by the user
import java.util.Scanner; // import Scanner class
public class grepperjava {
public static void main(String[] ARGS)
{
System.out.println("\nPlease enter a number, and the loop will iterate input times.");
int input;
Scanner var = new Scanner(System.in); // Create scanner object, so user-input may be read
input = var.nextInt();
var.close();
for(int i = 0; i < input; i++)
{
System.out.println("This will print " + input + " times");
}
}
}
Thank you!

for(int i = 0; i < 10; i++)
{
//do something
//NOTE: the integer name does not need to be i, and the loop
//doesn't need to start at 0. In addition, the 10 can be replaced
//with any value. In this case, the loop will run 10 times.
//Finally, the incrementation of i can be any value, in this case,
//i increments by one. To increment by 2, for example, you would
//use "i += 2", or "i = i+2"
}
Thank you!
