How do i add two , 2-dimensional arrays in java?
826904
for (int i = 0; i < arrayA.length; i++)\nfor (int j = 0; j < arrayA[0].length; j++)\n  arrayC[i][j] = arrayA[i][j] + arrayB[i][j];\n\nSystem.out.println("  Values for arrayC");\nfor (int i = 0; i < arrayC.length; i++)\n   for (int j = 0; j < arrayC[0].length; j++)\n   {\n      System.out.print(arrayC[i][j]);\n      if(j < arrayC[0].length - 1)\n        System.out.print("   ");\n      else\n        System.out.println("");\n  }

what u have done in ur coding is, simply get and input from the user and then display it...\nwhat u need to do is save those inputs into an array..so that the user will be able to at least enter the information about 100 Hobbits\nU can use a two dimensional array to save the user inputs..\nAlso the user should be given the option to continue entering more hobbit information, or view already entered information..

What you are trying to do is actually part of a larger sorting algorithm called "Merge Sort".\n\nhere is an example:\nhttp://mathbits.com/MathBits/CompSci/Arrays/Merge.htm\n\nYou would keep merging the sorted arrays in set K into the "master" sorted array.  Thus, you would only be working with two sorted arrays at any one time.\n\nSearch the net for "Merge Sort" for other implementations.

1>INPUT 1\n2>STORE 1 in A\n3>STORE 1 in B\n4>ADD A to B\n5>STORE A\n6>DISPLAY A\n\nThat's total of 6 steps. If you have 2 different numbers than you will have one more step of INPUT 'X' so it will be total 7 steps in that case.

It may be easier to use an array list.\n\n  Dim al As New ArrayList()\n\n   al.Add("This")\n   al.Add("Is")\n   al.Add("My")\n   al.Add("New")\n   al.Add("ArrayList")\n   al.Add("Control")\n\n   Console.WriteLine("Before Sort:")\n   WriteElements(al)\n\n   al.Sort()\n\n   Console.WriteLine("After Sort:")\n   WriteElements(al)\n End Sub\n\n Private Sub WriteElements(ByVal al As ArrayList)\n   Dim i As Integer\n   \n   For i = 0 To al.Count - 1\n     Console.WriteLine(CStr(al.Item(i)))\n   Next

It's been a while since I did anything in Java but I'm fairly certain it's just this:\n\nfile.add(new MenuItem("Print"));\nfile.add(new MenuItem("-"));\nfile.add(new MenuItem("Exit"));\n\n..give it a shot.

In order to understand the difference, you must also know what they have in common. Both of them are lists in which the length can vary. What I mean by that is that, unlike an array, which has a fixed length when it is first created, these lists can both "increase" in size when adding elements to them.\n\nThe difference is in how they implement it.\nAn ArrayList internally uses an array (or rather series of arrays) to store its elements. The ArrayList will make the determination whether to allocate more arrays in which to store elements when adding elements.\nA LinkedList stores its elements as a series of "node objects" of which each one has a reference to the element that comes after and the element that comes before (if any). (For the record, the Java implementation is a "Doubly linked list".)\nBoth have their advantages and disadvantages.\nArrayLists are very fast when it comes to finding elements based on index (because they use arrays internally). LinkedLists are much slower.\nLinkedLists are much more efficient at using memory (but in the Java implementation, this is not such a big deal). They are also more efficient at adding and removing elements from the beginning of the list, thus making them more suitable for stack implementations.

I hope you can understand the pseudocode, it's pretty loose.\n\nConstruct two arrays P and Q.\nLet P be empty, and Q contain the n numbers you want to permute.\nTo start, call the function PrintPermute below passing in the arrays P and Q.\n\nPrintPermute( P, Q)\n{\n  if Q is empty, print the values in P in order and return\n  else\n\n  for each value q in Q,\n  {\n       Create the strings P' and Q' where P' = P + q and Q' = Q - q\n       Call PrintPermute(P', Q')\n }\nreturn\n}

You don't need two msgboxes.\n\nfor intCounter = 0 to lstListBox.Listcount-1\n   msgbox lstListBox.List(intCounter)\nnext intCounter\n\nthat should do it.

The difficult thing here is reading and writing the numbers. They must be transformed from ASCII and then the result transformed back to ASCII.I found a program that calculates the sum of 2 numbers.I hope it helps.

Sounds like a question that I had back in cegep. I guess it depends on how your teacher wants you to do it. You can create an array of type string, or create a linked list. You can even store it in a database or textfile. Depends entirely on what you're going to do with it, and what your teacher wants.\n\nEric

Try the Java reference library.  Here is a link to it online:

either do direct value initialization inside the bracket\n\nint MyArrayD[N]={0,0,0,0,0,0,0,0..};\n\nor \n\nfor(int i = 0; i <N; i++}\nMyArrayD[i]=0;

It depends on the object.  You find the area of all the sides and then add them together.

Pseudocode, I'm not up on my Java syntax:\n\nint sum=0;\nfor(int i=0;i<array.size;i++)\n  sum+=array[i];
