Java程序以生成一定范围内的随机数数组并获取最小值和最大值
首先，创建一个双精度数组-
double[] val = new double[10];
现在，在循环中生成并显示随机数，循环直到上述数组的长度。我们在这里将nextInt用于随机数-
for (int i = 0; i < val.length; i++) {
val[i] = new Random().nextInt(100);
System.out.println(val[i]);
}现在，获取最小值和最大值。将随机数组的每个值与MIN和MAX值进行比较-
double min = Double.MAX_VALUE;
double max = Double.MIN_VALUE;
for (int i = 0; i < val.length; i++) {
if (val[i] < min)
min = val[i];
if (val[i] > max)
max = val[i];
}示例
import java.util.Random;
public class Demo {
public static void main(String[] args) {
double[] val = new double[10];
double min = Double.MAX_VALUE;
double max = Double.MIN_VALUE;
System.out.println("Random number array...");
for (int i = 0; i < val.length; i++) {
val[i] = new Random().nextInt(100);
System.out.println(val[i]);
}
for (int i = 0; i < val.length; i++) {
if (val[i] < min)
min = val[i];
if (val[i] > max)
max = val[i];
}
System.out.println("Minimum element = " + min);
System.out.println("Maximum element = " + max);
}
}输出结果
Random number array... 75.0 42.0 47.0 71.0 12.0 70.0 86.0 97.0 14.0 41.0 Minimum element = 12.0 Maximum element = 97.0
