Submissions

This assignment requires you to submit three Java source code files with these exact names:

TwoMethodsA$03.$java

GreatestAndLeast.java

RandomsInFile.java

General Requirements

All files you are turning in must be signed. Please add your name to the source code in comments.

Add comments to the source code you are writing:

Use Descriptive variable names. Otherwise, Describe the purpose of every variable

Explain the algorithm you are using for solution

Any methods except for main$()$ must have a Java Doc comment.

Uncommented work loses up to $10$ points.

Turn in only the source code $$ all files with $.$java extension. Make sure the source code files named correctly.

Two Methods getLargestDigit$()$ method

Write a method that takes an integer number $($either positive or negative$),$ and finds and returns the largest digit in that number.

Requirements:

Do not use arrays in your solution.

Do not convert integer into a string in order to extract digits. Use $\%$ operator instead.

Make sure to write method code according to the specifications and test them using unit tests provided in TwoMethodsA$03.$zip Download TwoMethodsA$03.$zip

Do not add any imports to the project $-$ all packages needed for solution are already imported.

Do not alter any of the tests. If your code is not passing a test, find and fix errors in your method implementation rather than changing the test code.

No partial credit will be given for a method that fails even one test.

Two Methods fractionSum$()$ method

Write a method that calculates and returns sum of fractions $1/2+2/3+...+$ n$/($n$+1)$ where value n is passed as parameter and defines the length of the pattern and the sum. The method returns $-1$ if the value of n is less than $1.$

Examples:

fractionSum$(1)=1/2$

fractionSum$(2)=1/2+2/3$

fractionSum$(3)=1/2+2/3+3/4$

fractionSum$(5)=1/2+2/3+3/4+4/5+5/6$

fractionSum$(0)=-1$
