Question

I need some help in 2 questions, thanks for your posts!
1. Can I join 2 or more chars in a string?
2. Can I return a array, like this?
    double[ ][ ] returnarray(){
        return darray[ ][ ];
    }When I try it gives-me this error:
DynamicArray.java [44:1] '.class' expected
return darray[ ][ ] ;
^
Thanks for your posts!

I�ve donne this subroutine, that is supose to return a array after creating it ( and with values inside it )
public class DynamicArray{
    private double[ ] [ ] darray;
    void dcreate(int num1, int num2);
        if(num1<1 || num2<1){
            System.out.println("System internal error: program needs to close!");
            System.exit(1);
        darray = new double[num1] [num2];
    void dadd(int num1, int num2, double toput){
        if (create==false){
            System.out.println("System internal error: program needs to close!");
            System.exit(0);
        if(darray.length -1>= num1 & darray[0].length-1 >= num2){
            darray[num1][num2]=toput;
    double[ ][ ] returnarray(){
        return darray [ ] [ ] ;
}But it gives-me this error:
DynamicArray.java [43:1] '.class' expected
return darray[][] ;
