WGU D335 Into to Python PA|Latest 2025 Update with complete solution

20.01 Practice Lab 1 (Introduction to Java)

INSTRUCTIONS:
Write a program that outputs the pattern shown below, ending with a newline. Each line of the pattern
contains 5 characters including whitespace.

OUTPUT:
H H
H H
HHHHH
H H
H H

SOLUTION (in red):

public class Lab {
public static void main(String[] args) {
/* Type your code here. */
System.out.println("H H");
System.out.println("H H");
System.out.println("HHHHH");
System.out.println("H H");
System.out.println("H H");
}
}

WALKTHROUGH:
Just pay attention to how many characters are required on each line and use System.println();

20.02 Practice Lab 2 (Multiplication)

INSTRUCTIONS:
For this lab you will use unit testing to check a null setting using assertions. Use the commented template
code provided to do the following:

Write a program that collects two integer inputs and assigns them to the variables starting_num and
multiplier. Multiply starting_num by multiplier and output the result. Repeat this process two more times,
each time multiplying the previous result by multiplier. The three product outputs should be separated by
a whitespace character, ending with a newline.

If the input is:
25
the output when starting_num = 2 is:
10 50 250

,SOLUTION (in red):

import java.util.Scanner;
public class LabProgram {
public static void main(String[] args) {
Scanner scnr = new Scanner(System.in);
/* Type your code here. */

int num1 = scnr.nextInt();
int num2 = scnr.nextInt();

int starting_num = num1;
int multiplier = num2;

int result1 = starting_num * multiplier;
int result2 = result1 * multiplier;
int result3 = result2 * multiplier;
System.out.println(result1 + " " + result2 + " " + result3);
}
}

OR

int starting_num = scnr.nextInt();
int multiplier = scnr.nextInt();

for (int i = 0; i < 3; i++) {
result *= multiplier;
System.out.print(result);

if (i < 2) {
System.out.print(“ “);
}
}
System.out.println();

20.03 Practice Lab 3 (Wedding Tables)
INSTRUCTIONS:
Write a program that calculates the number of full tables for a wedding event, based on the number of
expected guests. Each full table will seat 10 wedding guests.

Collect one integer input and assign it to the variable guests. Using integer division, calculate the total
number of tables that will be filled. The variable tableSize has been declared and initialized and the
variables guests and tablesFilled have been declared in the template code.

, Output the number of tables filled, ending with a newline. Ensure your program output matches the
example formatting below and works for a variety of input values.

If the input is:
340

the output is:
Tables filled: 34

Alternatively, if the input is:
349

the output is:
Tables filled: 34

SOLUTION (in red):

import java.util.Scanner;
public class LabProgram {
public static void main(String[] args) {
Scanner scnr = new Scanner(System.in);
int tableSize=10, guests, tablesFilled;
/* Type your code here. */

guests = scnr.nextInt();
tablesFilled = guests / tableSize;
System.out.println("Tables filled: " + tablesFilled);
}
}

20.04 Practice Lab 4 (Name / Salary)
INSTRUCTIONS:
Write a program that takes a full name, age, and salary as inputs on separate lines. Output a formatted
message containing the inputs, ending with a newline. Ensure your program output matches the example
formatting below and works for a variety of input values.

If the input is:
Pat Ford
35
60,000

the output is:
Pat Ford is 35 and makes $60,000.
