如何在一行而不是多个中更新？

Question

Simple, I just want a code that (instead of printing out individual lines of text in the console) update just one line of text with the new values, or "replace" it.

Current Code:

//this code was expanded into a more configurable version
//original author is zengr

public final class EnumRandValue {

public static final void main(String... aArgs){
int min = 12;
int max = 157;
int ints = 1000;
//how many numbers to generate?

int enumeration = 1;
int maximumints = 1000;
//advanced users only!

log("Generating " + ints + " random integers in range of " + (min-1) + " and " + (max-1) + ".");

//note a single Random object is reused here
if(min < max || min != max) {
Random randomGenerator = new Random();
for (int idx = 1; idx <= ints; ++idx){
  int randomInt = randomGenerator.nextInt(max);
  log("E" + enumeration++ + ": " + randomInt);
  if(enumeration >= maximumints) {
      String breakmsg = "Exceeded enums limit (" + maximumints + ").";
      log(breakmsg);
      return;

  } else if(min >= max) {
  String breakmsg = "Invalid min/max values.";
  log(breakmsg);
  return;     

  } else {
  //really nothing happens here
  //some code was excluded

I'm assuming that your log() method is a static method that prints the string that is passed to it.

In that case if you just want to print the last line of your for loop check the below condition before your print.

if(idx==ints)
log("E" + enumeration++ + ": " + randomInt);
