Yea I am reading the stuff at java.com and I am confused about this part could someone explain in more detail what is what... I am lost especially with the array over an array I do not understand what is 1 and 2 etc I understand arrays just not the double... or at least the example... also the array copy I am confused about that maybye it is the way they named there variables?

heres what I do not understand...




You can also declare an array of arrays (also known as a multidimensional array) by using two or more sets of square brackets, such as String[][] names. Each element, therefore, must be accessed by a corresponding number of index values.

In the Java programming language, a multidimensional array is simply an array whose components are themselves arrays. This is unlike arrays in C or Fortran. A consequence of this is that the rows are allowed to vary in length, as shown in the following MultiDimArrayDemo program:

class MultiDimArrayDemo {
public static void main(String[] args) {
String[][] names = {{"Mr. ", "Mrs. ", "Ms. "},
{"Smith", "Jones"}};
System.out.println(names[0][0] + names[1][0]); //Mr. Smith
System.out.println(names[0][2] + names[1][1]); //Ms. Jones
}
}

The output from this program is:
Mr. Smith
Ms. Jones

Finally, you can use the built-in length property to determine the size of any array. The code

System.out.println(anArray.length);

will print the array's size to standard output.
Copying Arrays
The System class has an arraycopy method that you can use to efficiently copy data from one array into another:
public static void arraycopy(Object src,
int srcPos,
Object dest,
int destPos,
int length)

The two Object arguments specify the array to copy from and the array to copy to. The three int arguments specify the starting position in the source array, the starting position in the destination array, and the number of array elements to copy.
The following program, ArrayCopyDemo, declares an array of char elements, spelling the word "decaffeinated". It uses arraycopy to copy a subsequence of array components into a second array:

class ArrayCopyDemo {
public static void main(String[] args) {
char[] copyFrom = { 'd', 'e', 'c', 'a', 'f', 'f', 'e',
'i', 'n', 'a', 't', 'e', 'd' };
char[] copyTo = new char[7];

System.arraycopy(copyFrom, 2, copyTo, 0, 7);
System.out.println(new String(copyTo));
}
}

The output from this program is:

Only had to read that ounce ^^ to get it thanks! ... Now the evil double arrays.... I do not understand what the smith and jones are doing under the list of array names is the line below the array declarings the 2nd [] array? Also the way it prints it out I do not understand how the []# + [][] blah prints it out?

class MultiDimArrayDemo {
public static void main(String[] args) {
String[][] names = {{"Mr. ", "Mrs. ", "Ms. "},
{"Smith", "Jones"}};
System.out.println(names[0][0] + names[1][0]); //Mr. Smith
System.out.println(names[0][2] + names[1][1]); //Ms. Jones
}
}

The output from this program is:
Mr. Smith
Ms. Jones

I do not know much java at all, but i have messed with c++ and vb so i can interpret how this works for the most part.

This is just spaced down. You can tell this by it doesnt have the end ;
{{"Mr. ", "Mrs. ", "Ms. "},
{"Smith", "Jones"}};

Really is like this:
{{"Mr. ", "Mrs. ", "Ms. "},{"Smith", "Jones"}};
0 1 2 0 1

Mr. = 0
Mrs. = 1
Ms. = 2

Smith = 0
Jones = 1

On this part: the // Mr. Smith and // Ms. jones are comments. They are not part of the code. This is like a compound array. "Double array or what ever javaj programmers call it."
System.out.println(names[0][0] + names[1][0]); //Mr. Smith
System.out.println(names[0][2] + names[1][1]); //Ms. Jones


names[0]<--Array [0]<--Mr. + names[1]<--Array [0]<--Smith
names[0]<--Array [2]<--Ms. + names[1]<--Array [1]<--Jones
