why would you use a forstatement in java code example

Example 1: how to make a loop in java

// 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);
}

Example 2: for loop java

for(/*index declaration*/int i=0; /*runs as long as this is true*/
   i<=5; /*change number at end of loop*/i++){
doStuff();

}
