i currently have a method that checks what is around the centre item in a 3x3 grid, if what is in the 8 adjacent positions is containing what i am checking for i want to mark that square on an array with length 7 as being 1.
to do this i need to create and return an array 开发者_高级运维in my method, is it possible to do this?
Not sure what is the problem. You mean this?
public int[] myMethod() {
//...
int[] res = new int[7];
//... set values ...
return res;
}
Declare the return type to be two dimensional array (int[][]
), create the array in your method and return that.
public int[][] getArray() {
int[][] myArray = new int[3][3];
// Populate array
return myArray;
}
