Java two dimensional array initialization
Two Dimensional Array in Java
Accessing and Processing the Elements of a two-Dimensional Array. You access and process the elements of a two-dimensional array in Java in the same way that the elements of a two-dimensional array are accessed and processed in C++. Example. Given the following two-dimensional array that holds 5 lab scores of 7 students:

And, since an array type is a first-class Java type, you can, in particular, have an array of arrays. For example, an array of ints is said to have the type int[]. This means that there is automatically another type, int[][], which represents an "array of arrays of ints". Such an array is said to be a two-dimensional array.

Nested Looping with Two-Dimensional Arrays. Nested looping is commonly used to process the elements of two-dimensional arrays. This initialization allocates enough memory to store 40 floating-point numbers—a two-dimensional array with five rows and eight columns. Java initializes all values to 0.0 when constructed. int. ROWS = 5; int. COLUMNS ...

A two-dimensional array in C++ and Java is a one-dimensional array of one-dimensional arrays that consist of the rows of the array. In addition to the one-dimensional arrays that represent the rows of the array, there is another array of pointers such that each element of this array holds the address of the first element of the corresponding ...

Example 8.3 Creating and explicitly initializing one-dimensional arrays. Create an array of the first 10 even integers beginning with the number two. Let us call the array evenNumbers, the the declaration, construction, and initialization is as follows: int evenNumbers[] = {2, 4, 6, 8, 10, 12, 14, 16, 18, 20}; Create an array of all the vowels.
