Examples of for loops

The for loop is used mainly to realize definite loops.

• for (int i = 1; i <= 10; i++) ...
  values assigned to i: 1, 2, 3, ..., 10
• for (int i = 10; i >= 1; i--) ...
  values assigned to i: 10, 9, 8, ..., 2, 1
• for (int i = -4; i <= 4; i = i+2) ...
  values assigned to i: -4, -2, 0, 2, 4
• for (int i = 0; i >= -10; i = i-3) ...
  values assigned to i: 0, -3, -6, -9

Example: Print the numeric code of the characters from 15 to 85.

for (int i = 15; i <= 85; i++) {
  char c = (char)i;
  System.out.println("i = " + i + " -> c = " + c);
}
