for(i:a) in java code example

Example 1: java for loop

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"
}

Example 2: java for loop

// 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");
        }
    }
}
