Document Summary

System continues on to the four jovian (jupiter-like) planets jupiter, saturn, We will study their key features, including their overall composition and internal structures; massive cloud systems giving rise to. Weather" and storms that can last for centuries; and magnetospheres larger than. The giant planets are also like solar-systems of their own, with 150+ moons orbiting them in total, presenting a large variety of worlds with unique structures and features. Jovian or, jupiter-like planets have features that are both similar and different from each other. After completing this lesson, you should be able to: features of jovian planets, overall composition, Jovian planets: variety of moons (sizes), geologic activity of galilean moons, recent activity and features on titan, Icy jovian moons versus inner terrestrial planets compare the overall composition of the jovian planets, noticing differences between jupiter and. Jovian planets and that of earth, in terms of strength and size: describe the overall distribution of moons around.

9. Write a method with the following header public static void replace (String oldFile, string newfile, char oldChar, char newChar) throws IOException This method opens the file whose name is given by the String parameter oldFile (the input file) for reading, and opens the file whose name is given by the string parameter newlile (the output file) for writing. It then reads every lime in the input file. For each line, it creates a new line identical to the original line, creept for the fact that all occurrences of char oldchar in the original String have been replaced by occurrences of char newchar in the new line. When the new line has been properly created, it write it to the output file. Once all the lines in the input file have been read and a corresponding line has been written to the output file, the method clases both files. Additional notes: • You MAY assume that none of the parameters this method accepts are null; in other words, your method does not have to handle the case where one or more of the parameters are null. You MAY assume that all the 10-related classes have already heen imported properly . Finally, because the replace() method is specified to throw an exception object of type TORxception, you MAY assume that I/O related problems will occur while reading from the input file or writing to the output file. In other words, your method DOES NOT have to check that no such problems occur, and DOES NOT have to manage Texceptions using try-catch blocks.

Your program will take an arithmetic expression as a String input. For Example:

“1+2*(3/4)”

“1+2*[3*3+{4–5(6(7/8/9)+10)–11+(12*8)]+14”

“1+2*[3*3+{4–5(6(7/8/9)+10)}–11+(12*8)/{13+13}]+14”

Program

Your program will determine whether the open brackets (the square brackets, curly braces and the parentheses) are closed in the correct order.

Outputs:

Output 1

1+2*(3/4)

This expression is correct.

Output 2

1+2*[3*3+{4–5(6(7/8/9)+10)–11+(12*8)]+14

This expression is NOT correct.

Error at character # 10. ‘{‘- not closed.

Output 3

1+2*[3*3+{4–5(6(7/8/9)+10)}–11+(12*8)/{13+13}]+14

This expression is correct.

Output 4

1+2]*[3*3+{4–5(6(7/8/9)+10)–11+(12*8)]+14

This expression is NOT correct.

Error at character # 4. ‘]‘- not opened.

Task 1

Solve the above problem using an array-based stack.

Task 2

Solve the above problem using a linked list-based stack.

Complete the following problem using concepts of STACK.

If you are using JAVA, you must include the main method as well which should test your other methods and print the outputs according to the tasks.

If you are using PYTHON, make sure your code has the methods invoked and proper printing statements according to the tasks.
