Let’s move right on to generating a random Integer with no bounds: @Test public void givenUsingPlainJava_whenGeneratingRandomIntegerUnbounded_thenCorrect() { int generatedInteger = new Random().nextInt(); } As you can see, it’s pretty close to generating a long. 4. Generate an Integer ...

Before Java 1.7, the most popular way of generating random numbers was usingnextInt.There were two ways of using this method, with and without parameters. The no-parameter invocation returns any of theintvalues with approximately equal probability. So, it’s very likely that we’ll get negativ...
