array length in Salesforce

Question

I'm getting error "Error Error: AddIMRConroller Compile Error: Initial term of field expression must be a concrete SObject: LIST at line 21 column 23" from below line of code .

string[] str1 = imrTable.split('\r\n'); System.debug( str1.length);

Answer 1

In Salesforce, you'd need to use size() method instead of length. This is something different than Java.

I believe that you're using an array and if in your visualforce page, you can use something like this:

{!oBjectArray.size==0}
