Write a Java method that takes two three-dimensional integer arrays and adds them componentwise.

Write a Java method that takes a two-dimensional ragged array as input and uses that array to print the following output: Two dimensional Ragged Array: ABCD EF G H I Then write a Java program to test your method.

Write the Java method averageOfDoubles that is passed an array of double values, and returns the average of the array values.You can assume the array length is a positive integer.

Using JAVA, write a method that swaps two rows of a two-dimensional array. The row indices to be swapped are passed as parameters to the method (Assume row indices are valid indices). Write a test program to demonstrate correct operation of the method.

Solution in Java Create a function that takes an array of increasing letters and return the missing letter. Examples missing Letter (["a", "b", "c", "e", "f", "g"]) → "d" missing Letter (["O", "Q", "R", "S"]) → "P"

Write the method printTail() method that accepts an array of integers and an integer index as parameters and prints all the array elements starting from the index passed. For example if printTail(x,5) is invoked, it should print all the elements of the array x starting at x[5].

Write a Java method that receives a two-dimensional array of primitive ints ( int [] [] ). The array can have any number of rows and any number of items per row. Also, the array can be "ragged" (not all rows have the same number of items). Have the method return the average of all of the items in the array as a primitive double.

Write a code in java print the largest number in array. Please add comments also and screenshot of output also.
