1.1 Code snippet. For getRandomNumberInRange(5, 10), this will generates a random integer between 5 (inclusive) and 10 (inclusive). private static int getRandomNumberInRange(int min, int max) { if (min >= max) { throw new IllegalArgumentException("max must be greater than min"); } ...
2. 生成随机整数：Random类中的ne某tInt(方法可以用来生成一个指定范围内的随机整数。例如，生成一个0到10之间的随机整数：int randomNumber = rand.ne某tInt(10);。3. 生成随机浮点数：使用Random类中的ne某tDouble(方法可以生成一个0到1之间的随机浮点数。例如，生成一个0到1之间的随机浮点数：double random...
2.1.java.lang.Math Therandommethod of theMathclass will return adoublevalue in a range from 0.0 (inclusive) to 1.0 (exclusive).Let’s see how we’d use it to get a random number in a given range defined byminandmax: int randomWithMathRandom = (int) ((Math.random() * (max - min...

Note:You might get a different output in the above program asMath.random()will generate a random number. Example 2: Generate random number between two numbers // generating random number in range [x, y) functiongetRandomNum(min, max){returnMath.random() * (max - min) + min; ...
