like you wrote ... the problem is line 76. the declaration:
public build2dArray(String[] otherArray)
this declaration misses the return-object-type. you have to write:
public String build2dArray(String[] otherArray)
... then you have to edit the return values:
line 99: return (String (city)); ... String (city) is interpreted as function call ... you can write: return city;
same issue at line 116
line 124: write return "";
... then you can compile the code.
