Methods of StringBuilder class

The StringBuilder class can be used to create mutable strings. The methods defined in the StringBuilder class are widely used to manipulate and concatenate strings. It is a non-synchronized class which has public methods that can be accessed by multiple threads. It is not thread-safe.

Problem Description - JAVA PROGRAMMING Use a Two-dimensional (3x3) array to solve the following problem: Write an application that inputs nine numbers, each of which is between 1 and 10, inclusive. Display the array after the user inputs each value. Rotate/flip the array by changing places. Make the rows columns and vice versa. You have to move the elements to their new locations. Remember to validate the input and display an error message if the user inputs invalid data. Documentation and the screenshot(s) of the results.

Recipe Program - Java ONLYI am looking to create a program that is a recipe holder. It needs to include at a minimum: At least 1 loop An Array or ArrayList At least 3 Java classes Use of methods The program would allow the user to (as part of a menu selection): Add a recipe Include ingredient list Instructions List all recipes that are in the program (array) Display a single recipe Search Recipes (option to view recipe selected) For example, searching for peanut butter cookie would bring up the recipe or multiple if the same name. The user could then select one of them to view the recipe. Search Recipes with a single ingredient (option to view recipe selected) For example: search for coconut and it would bring up coconut cream pie and German chocolate cake. The user could then select one of them to view the recipe. Close application Also need the program in a UML diagram.
