2.13.2: Get random numbers. JAVA
Type two statements using nextInt() to print two random integers between (and including) 0 and 9. End with a newline. Ex: 5 7 Note: For this activity, using one statement may yield different output (due to the interpreter calling randGen.nextInt() in a different order). Use two statements for this:
import java.util.Scanner;
import java.util.Random;
public class DiceRoll {
public static void main (String [] args) {
Scanner scnr = new Scanner(System.in);
Random randGen = new Random();
int seedVal;
seedVal = scnr.nextInt();
randGen.setSeed(seedVal);
// Solution goes here//
}
}
import java.util.Scanner;
import java.util.Random;
public class DiceRoll {
public static void main (String [] args) {
Scanner scnr = new Scanner(System.in);
Random randGen = new Random();
int seedVal;
seedVal = scnr.nextInt();
randGen.setSeed(seedVal);
// Generate random integers in range 0 to 9
System.out.println(randGen.nextInt(10));
System.out.println(randGen.nextInt(10));
}
}

(Java Zybooks) Given numRows and numColumns, print a list of all seats in a theater. Rows are numbered, columns lettered, as in 1A or 3E. Print a space after each seat, including after the last. Use separate print statements to print the row and column. Ex: numRows = 2 and numColumns = 3 prints: 1A 1B 1C 2A 2B 2C import java.util.Scanner; public class NestedLoops { public static void main (String [] args) { Scanner scnr = new Scanner(System.in); int...

Write a for loop to print all NUM_VALS elements of array hourlyTemp. Separate elements with a comma and space. Ex: If hourlyTemp = {90, 92, 94, 95}, print: 90, 92, 94, 95 Your code's output should end with the last element, without a subsequent comma, space, or newline. import java.util.Scanner; public class PrintWithComma { public static void main (String [] args) { Scanner scnr = new Scanner(System.in); final int NUM_VALS = 4; int[] hourlyTemp = new...
