> so we cant copy into twoD array rowwise?I didn't say that. I meant that the code you posted can never throw any exception because it cannot be compiled.

Although it doesn't make a lot of sense, this will compile:int n = 10;

String b= "acd:tyt:rt";

String[][] a= new String[n][];

for(int i = 0; i < n; i++){

a[i] = b.split(":");

}

String.split(String) does return an array of Strings, so this code will compile; now what's your problem? This code is different than the OP and shouldn't give you any exceptions. The result of this code, viewed as a grid should be

[["acd"]["tyt"]["rt"]

["acd"]["tyt"]["rt"]

["acd"]["tyt"]["rt"]]

What do you want to happen?
