ACTIVITY
2.18.3: Fixed range of random numbers.
Type two statements that use nextInt() to print 2 random integers between (and including) 100 and 149. End with a newline. Ex:
112 102
My Previous Incorrect Attempt :
import java.util.Scanner;
import java.util.Random;
public class RandomGenerateNumbers {
public static void main (String [] args) {
Random randGen = new Random();
int seedVal;
seedVal = 4;
randGen.setSeed(seedVal);
/* Your solution goes here */
int first = randGen.nextInt(10);
int second = randGen.nextInt(10);
System.out.println(first*seedVal*14);
System.out.println(second*seedVal*(51/4)+6);
}
}
MUST BE USED CODE TEMPLATE:
import java.util.Scanner;
import java.util.Random;
public class RandomGenerateNumbers {
public static void main (String [] args) {
Random randGen = new Random();
int seedVal;
seedVal = 4;
randGen.setSeed(seedVal);
/* Your solution goes here */
}
}

Answer 1

Replace /* Your solution goes here */ with:

System.out.println(randGen.nextInt(49) + 100);

System.out.println(randGen.nextInt(49) + 100);

Step-by-step explanation:

Required

Statements to print two random numbers between 100 and 149 (both inclusive)

First, the random numbers must be generated. From the template given, the random object, randGen, has been created.

The syntax to then follow to generate between the interval is:

randGen.nextInt(high-low) + low;

Where:

high = 149 and low = 100

So, the statement becomes:

randGen.nextInt(149 - 100) + 100;

randGen.nextInt(49) + 100;

Lastly, print the statements:

System.out.println(randGen.nextInt(49) + 100);

System.out.println(randGen.nextInt(49) + 100);
