what is the purpose of a for loop 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: for() in java

public class name_of_java_app {
public static void main(String[] args) {
  int value = 4;
  string whatever_value = "whatever_val";
  // The value can be whatever you want.
  for(int name_of_int; name_of_int < value; name_of_int++) {
  System.out.println(whatever_value + name_of_int);
  }
  // The output will be 0 1 2 3 4 whatever_val
  // You can put any data value such as char or short but not boolean
}
}
