How can I generate two separate outputs using Random in Java
To generate two separate outputs, at first create a new Random object −
private static final Random r = new Random();
Now, let us declare a value −
int val = 5;
Loop from the value till 100 and generate random numbers between 1 to 100 −
while (val<= 100) {
System.out.printf("%-4d", r.nextInt(20) * 1);
if (val % 5 == 0) {
System.out.println();
}
val++;
}In the same way, generate a different output with different conditions.
Example
import java.util.Random;
public class Demo {
private static final Random r = new Random();
public static void main(String[] args) {
int val = 5;
while (val<= 100) {
System.out.printf("%-4d", r.nextInt(20) * 1);
if (val % 5 == 0) {
System.out.println();
}
val++;
}
System.out.println();
val = 20;
while (val<= 100) {
System.out.printf("%-4d", r.nextInt(10 * (20)));
if (val % 5 == 0) {
System.out.println();
}
val++;
}
}
}Output
1 18 2 1 16 0 8 15 1 6 0 19 13 10 14 16 13 5 16 5 14 16 13 14 1 2 14 11 11 12 9 18 11 16 2 3 4 17 8 8 19 7 0 15 14 11 10 12 4 17 13 19 17 1 12 8 1 14 6 3 6 10 10 7 3 4 18 19 12 7 6 3 11 2 6 1 4 18 9 11 2 16 16 3 19 18 18 14 2 18 2 13 7 8 8 2 72 72 53 2 60 19 187 57 138 16 124 20 67 0 94 3 51 127 84 146 126 86 125 29 68 30 124 61 88 127 11 87 139 30 156 12 39 133 117 11 179 124 199 1 91 117 44 43 160 181 74 171 187 167 192 174 49 106 172 118 44 19 95 155 199 69 54 84 27 4 30 51 122 122 122 47 63 193 76 115 56
