Question

Write a method that will receive 2 numbers as parameters and will return a string containing the pattern based on those two numbers. Take into consideration that the numbers may not be in the right order.

Note that the method will not print the pattern but return the string containing it instead. The main method (already coded) will be printing the string returned by the method.

Remember that you can declare an empty string variable and concatenate everything you want to it.

As an example, if the user inputs "2 5"

The output should be:

2
3 3
4 4 4
5 5 5 5

Answer 1

To solve this problem, you can define a method that takes two numbers as parameters. Inside the method, you can use a loop to create a pattern of numbers based on the given numbers. Finally, you can return the pattern as a string and print it in the main method.

Step-by-step explanation:

To solve this problem, you will need to define a method that takes two numbers as parameters. Inside the method, you can use a loop to iterate through the numbers and concatenate a pattern of numbers to an empty string variable. Here's an example of how you can implement the method:

public static String createPattern(int num1, int num2) {
String pattern = "";
int start = Math.min(num1, num2);
int end = Math.max(num1, num2);

for (int i = start; i <= end; i++) {
for (int j = 0; j < (i - start + 1); j++) {
pattern += i + " ";
}
pattern += "\\";
}

return pattern;
}

In this example, we first determine the start and end numbers by using the Math.min() and Math.max() functions. Then, we iterate through the range of numbers from start to end. For each number, we concatenate it to the pattern string multiple times, depending on its position in the sequence. Finally, we return the pattern string.

To use this method, you can call it from the main method and print the returned string:

public static void main(String[] args) {
int num1 = 2;
int num2 = 5;
String pattern = createPattern(num1, num2);
System.out.println(pattern);
}

This will output the pattern:

2
3 3
4 4 4
5 5 5 5
