Question

I have loop for:

for (int i = 1; i < 2000; i++)

How I can change this loop that instead of int < 2000 I can get time:

for (int i = 1; i < 2000(miliseconds); i++)

I want to do this loop until time is less then 2000 miliseconds.I mean that this loop must working for 2 seconds and after 2 sec break.

In loop I doing some operations. I save position of cursor. I want save that position for 2 seconds.

Assuming you want to do something in a loop until 2000ms has passed:

long then = new Date().getTime() + 2000/*ms*/;
do {
  // Do some work here...
  long now = new Date().getTime();
} while (now < then);

[Edit] As commenter @CheJami points out, there’s no need to create a Date object since you can get the current time in milliseconds directly:

long then = System.currentTimeMillis() + 2000/*ms*/;
do {
  // Do some work here...
  long now = System.currentTimeMillis();
} while (now < then);

This strategy will likely result in better performance overall since there is no need to repeatedly create new objects and eventually garbage collect them.
