I want to ask that can we generate random numbers in Java without any predefined classes (such as Random.class) and writing the code manually. If anyone can please atta
Generate a random number between 5.0 and 7.5 x1 <- runif(1, 5.0, 7.5) # 参数1表示产生一个随机数 x2 <- runif(10, 5.0, 7.5)# 参数10表示产生10个随机数 Generate a random integer between 1 and 10 x3 <- sample(1:10, 1) # 参数1表示产生一个随机数 x4 <- sample(1:10, 5, replace...
