For Loop?

1. Repeated pattern

// for (initial; condition; update) { code to execute; } // end of for

// print 0 to 9
for (int i = 0; i < 10; i++) {
  System.out.println("i : " + i);
} // end of for

// print the only even numbers between 1 to 10
for (int i = 1; i <= 10; i++) {
  if (i % 2 == 0) {
  System.out.println("even number : " + i);
  } // end of if
} // end of for

// print the total of all the number from 1 to 100
int result = 0;
for (int i = 1; i <=100; i++) {
  result += 1;
} // end of for
System.out.println("Total : " + result);

// print the total of all the odd number from 1 to 1000
int result = 0;
for (int a = 1; a <=1000; a++) {
  if (a % 2 != 0) {
    result += a;
  } // end of if
} // end of for
System.out.println("Total : " + result);

// get two values from user and 
// print the total of all the odd number from value 1 to value 2
