1.) A two dimansional array is a collection of a fixed number of components arranged in rows and columns, all components are the same type.
2.) To access the components of a two dimensional array you need two indices one for row and one for column.
3.)
1)A two-dimensional array uses columns and rows to create a grid like input system.
2)Each two-dimensional array must be declared as a primitive data type(int,double,) or a String.
3)Assignment into a variable in a two-dimensional array isdeclared as NameOfArray[row#][column#]= value.
1)Which comes first in declaring a two-dimensional array, columns or rows?
2)If a array is set to a string but has numbers assigned to locations, can they be parsed into doubles or ints?
(This would make arrays even more useful as one could put names with numbers in the same rows/columns)
1)Two-dimensional arrays do the same job as one-dimensional arrays but instead of having a new array for each row, the two-dimensional array combines them together to create a grid, saving typing time and openign up more options for how to use the input data.
1.To process ragged arrays you must know the exact number of columns for each row.
2.A two-dimensional array can be processed in these ways: process entire array, process a particular row of the array, called row processing, and process a particular column of the array, called column processing.
3.The java code to revers4e the diagnols works for any square two-dimensional array.
1.How do you find the largest possible element in each row or column.
2.What is reversing the diagnols used for.
1. This is some helpfull information for doing our final project.
1.) Just like in a one-dimensional array you can also use the instance variable length to determine the number of rows as well as columns.
2.)You can specify a different number of columns for each row.
3.)Arrays in which the number of columns in each row are not the same are called ragged arrays.
1.)Is there any benefits to using a ragged array over a regular array?
2.)Why would you want to reverse the diagonals?
1.) I hope that this added information on two dimensional arrays will help out on the final project.
3.)To access the components of a two-dimensional array, you need a pair of indices.
2.)Two dimensional arrays can be passed as parameters to a method.
1.)Two-dimensional arrays can be annalyzed with maximum and minimal values being able to be caluculated.
2.)Are there any benefits in a ragged array over a regular array?
1.) Whats the benefit of reversing the code of a square array?
1.)Two dimensional arrays are very useful for sorting data…. It makes labs such as the football employees lab very managable.
1) The first int in the [] represents the number of rows and the second [] represents the number of columns
2) To access the components of a two dimensional array you need two sets of indices, one for the row and one for the column.
3) Java allows you to create a two dimensional array that has different sized rows as well.
1) What is switching diagonals?
2) Could we take the data straight from a two dimensional array and graph it or do we need another program such as excel?
1) Sorry I’m so late on this post. This chapter has a lot to do with our final project which I still need to start XD.

1.) The java code that will reverse the diagonals works for any square two-dimensional array.
2.) Array: A collection of a fixed number of elements arranged in ‘n’ dimensions , called an “n-dimensional array”.
3.) When storing a two-dimensional array in computer memory, Java uses the row order form.
1.) Can two dimensional arrays be initialized when its declared?
2.) How can switching the diagonals be useful.
1.) Your class was awesome and I will never forget our time together.
