Example of a FOR Loop

public class Test {

   public static void main(String args[]) {

      for(int x = 10; x < 20; x = x + 1) {
         System.out.print("value of x : " + x );
         System.out.print("
");
      }
   }
}

what are for loops

# There are 2 types of loops in python
# while loops and for loops
# a while loops continues for an indefinite amount of time
# until a condition is met:

x = 0
y = 3
while x < y:
    print(x)
    x = x + 1

>>> 0
>>> 1
>>> 2

# The number of iterations (loops) that the while loop above
# performs is dependent on the value of y and can therefore change

# below is the equivalent for loop:
for i in range(0, 3):
    print(i)

>>> 0
>>> 1
>>> 2

# The for loop above is a definite loop which means that it will always
# loop three times (because of the range I have set)
# notice that the loop begins at 0 and goes up to one less than 3.
