Java Random Class:
| We can use the Eclipse IDE for this example. If you do not know about it then follow this link- How to Install Eclipse For Java and create a program in it. |
Java’s Random class generates sequences of numbers that, by the most stringent technical standards, are “almost random”. To use the correct terminology, the Random class creates a pseudo-random sequence of numbers.
Constructor for Java Random Class:
| Constructor | Description |
|---|---|
| Random() | Creates a new random number generator. |
| Random(seed:long | Creates a new random number generator using a single long seed. |
Java Random Class Methods:
| Method | Description |
|---|---|
| nextInt() | Returns the random integer value. |
| nextInt(n) | Returns the random integer value from the range 0 to n. |
| nextLong() | Returns a random long value. |
| nextDouble() | Returns a random double value. |
| nextFloat() | Returns a random float value. |
| nextBoolean() | Returns a random boolean value. |
