RandomLong

Description

The RandomInteger class allows you to generate random integer values.

Static methods

nextInteger

Generates an integer in the range [‘min’, ‘max’]. If ‘max’ is omitted, then the range will be set to [0, ‘min’].

public static long nextLong(long minValue, long maxValue)

• minValue: long - minimum value of the long that will be generated.

If ‘max’ is omitted, then ‘max’ is set to ‘min’ and ‘min’ is set to 0.

• maxValue: long - (optional) maximum value of the float that will be generated. Defaults to ‘min’ if omitted.
• returns: long - generated random integer value.

updateInteger

Updates (drifts) a long value within a specified range.

public static long updateLong(long value, long range)

• value: long - long value to drift.
• range: long - (optional) range. Default: 10% of the value
• returns: long - updated long value.

Examples

 {
 long value1 = RandomLong.nextLong(5, 10);     // Possible result: 7
 long value2 = RandomLong.nextLong(10);        // Possible result: 3
 long value3 = RandomLong.nextLong(10, 3);   // Possible result: 9
 }
