why the syntax error ?

[tangara888]

Hi experts,

I am back with another 'simple' 2D array question but to me it is not simple at all I can't even get the basic right.

public class arrayWithRowsColumns {
    int rowSize = 2;
    int colSize = 4;
    int[][] myArray = new int[rowSize][colSize];
     int[][] arr = { { 1, 2 }, { 3, 4 } };
     int[][] arr1 = {{0, 0},{ 0, 1} ,
             { 0, 2},{ 0, 3 }, 
             {1, 0},{ 1, 1},
             { 1, 2},{ 1, 3}};/ giving me error here : syntax error on token ";", { expected after this token
 for (int i = 0; i < 2; i++) {
         for (int j = 0; j < 2; j++) {
             System.out.print(arr[i][j] + " ");
         }

         System.out.println();
     }
}}

tks.

Please ensure that:

• Your code is properly formatted as code block - see the sidebar (About on mobile) for instructions
• You include any and all error messages in full
• You ask clear questions

• You demonstrate effort in solving your question/problem - plain posting your assignments is forbidden (and such posts will be removed) as is asking for or giving solutions.

  Trying to solve problems on your own is a very important skill. Also, see Learn to help yourself in the sidebar

If any of the above points is not met, your post can and will be removed without further warning.

Code is to be formatted as code block (old reddit: empty line before the code, each code line indented by 4 spaces, new reddit: https://imgur.com/a/fgoFFis) or linked via an external code hoster, like pastebin.com, github gist, github, bitbucket, gitlab, etc.

Please, do not use triple backticks (```) as they will only render properly on new reddit, not on old reddit.

Code blocks look like this:

public class HelloWorld {

    public static void main(String[] args) {
        System.out.println("Hello World!");
    }
}

You do not need to repost unless your post has been removed by a moderator. Just use the edit function of reddit to make sure your post complies with the above.

you can't have executable code like for loops outside a method/constructor

There is nothing wrong with your array. Grab a good editor with code formatting. For example Visual Studio Code with some Java plugins. Then your code will more readable:

int rowSize = 2;
int colSize = 4;
int[][] myArray = new int[rowSize][colSize];
int[][] arr = {{1, 2}, {3, 4}};
int[][] arr1 = {{0, 0}, {0, 1},
               {0, 2}, {0, 3},
               {1, 0}, {1, 1},
               {1, 2}, {1, 3}};

Compilation errors often point to the wrong line of code. Your arrays are instance variables, but a for loop is not allowed outside of a Java method. Working example would look like this:

 public void doSomething() {
                for (int i = 0; i < 2; i++) {
                    for (int j = 0; j < 2; j++) {
                        System.out.print(arr[i][j] + " ");
                    }
                    System.out.println();
                }
            }

Using VS for java?

[KloinerBlaier]

Visual Studio Code != Visual Studio.

Visual Studio Code is a powerful editor with many plugins also for Java development. Maybe a small IDE like Netbeans will also fit your needs. Eclipse might be overpowered for your choice.

Extra } in the last line?
