Java Utililty Methods Random Int

List of utility methods to do Random Int

Description

The list of methods to do Random Int are organized into topic(s).

Method

intrandomInt(int min, int max)
random Int
return (int) (min + Math.random() * (max - min));
intrandomInt(int mn, int mx)
Return a random int in a specified range.
double d = Math.random();
return (int) (mn + (mx + 1 - mn) * d);
intrandomInt(int n)
random Int
return (int) (Math.random() * n);
intRandomInteger()
Random Integer
return 2;
IntegerrandomInteger(final int upperRange)
Returns a random Integer within the range 0 to upperRange
return (int) (Math.random() * upperRange);
intrandomInteger(int low, int high)
Returns an integer value with a positive sign, greater than or equal to low and less than or equal to high.
Note: low limit is inclusive and high limit is also inclusive.
The formula used in this method is:
randomInteger = (int) (Math.random() * (high + 1 - low)) + low; (low: Inclusive, high: Inclusive)
return (int) (Math.random() * (high + 1 - low)) + low;
intrandomInteger(int min, int max)
random Integer
return (int) (min + Math.random() * (max - min));
intrandomIntFromInterval(int min, int max)
random Int From Interval
return (int) Math.floor(Math.random() * (max - min + 1) + min);
intrandomIntFromRange(int min, int max)
Generates random int value from the specified range of int numbers
return min + (int) (Math.random() * ((max - min)));
intrandomIntInInterval(int lower, int upper)
random Int In Interval
return (int) randomFloatInInterval(lower, upper);
