String getRange(int stop)

  • Description

    • Given an integer, stop, return a String concatenation of all integers between 0 up to and not including stop.

      Example

  • Sample Script

    // : Given
    int stop = 11;
    
    // : When
    String outcome = NumberUtilities.getRange(stop);
    
    // : Then
    System.out.println(outcome);

String getRange(int start, int stop)

  • Description

    • Given two integers, start, and stop, return a String concatenation of all integers between start up to and not including stop.

      Example

  • Sample Script

    // : Given
    int start = 5;
    int stop = 11;
    
    // : When
    String outcome = NumberUtilities.getRange(start, stop);
    
    // : Then
    System.out.println(outcome);

String getRange(int start, int stop, int step)

  • Description

    • Given three integers, start, stop, and step return a String concatenation of all integers between start up to and not including stop.

      Example

  • Sample Script

    // : Given
    int start = 5;
    int stop = 20;
    int step = 5;
    
    // : When
    String outcome = NumberUtilities.getRange(start, stop, step);
    
    // : Then
    System.out.println(outcome);

String getEvenNumbers(int start, int stop)

  • Description

    • Given two integers, start, and stop, return a String concatenation of all even integers between start up to and not including stop.

      Example

  • Sample Script

    // : Given
    int start = 5;
    int stop = 20;
    
    // : When
    String outcome = NumberUtilities.getEvenNumbers(start, stop);
    
    // : Then
    System.out.println(outcome);

String getOddNumbers(int start, int stop)

  • Description

    • Given two integers, start, and stop, return a String concatenation of all even integers between start up to and not including stop.

      Example

  • Sample Script

    // : Given
    int start = 5;
    int stop = 20;
    
    // : When
    String outcome = NumberUtilities.getOddNumbers(start, stop);
    
    // : Then
    System.out.println(outcome);

String getExponentiations(int start, int stop, int exponent)

  • Description

    • Given three integers, start, stop, and exponent, return a String concatenation of all values, raised to the specified exponent, between start up to and including stop.

      Example

  • Sample Script

    // : Given
    int start = 1;
    int stop = 4;
    int exponent = 3;
    
    // : When
    String outcome = NumberUtilities.getExponentiations(start, stop, exponent);
    
    // : Then
    System.out.println(outcome);
