I find this error:
Incompatible types
<"Cetera","Omosh","2-5-1987">
required:String []
Found: String.
Somebody shade some light please.
Best Regards,
Betny.

[JamesCherrill]

Assuming this error is around line 88 (and next time please post the line number with the error messages!) you define a 3-dimensional array,, but try to initialise it with data in the form of a 2-dimensional array. So when it looks inside the 2d array it expects to find one more level of array, but all it finds is a String.

[betny]

Hallo, It does not show the line number where the error is located, Please still having difficulties, how am i supposed to initialize the data in 3-dimensional.
Best regards,
Betny.

[JamesCherrill]

Look again, compiler and runtime messages do show the line number.

Without a proper statement of what this code is supposed to do I can't comment on how to reconcile your 2d data with your 3d array. But all the following statements seem to have the third index as [0] all the time, so maybe the third dimension is not needed???

[betny]

Thanx alot, yap the third index is not needed. I tried it and it worked, how am I supposed to populates the multi-dimensional array with data and another method that shows the contents of the multi dimensional array.
For example:

private void personalDetails() {

logger.debug( "personalDetails()" );

String personArray [][] =
{
{ "John", " Muray", "1-10-1982" },
{ "Peter", " Kamau", "2-5-1987" },
{ "Mary", " Wambui", "8-5-1988" },
{ "Bethu", " Kips", "8-8-1987" },
{ "Cetera", " Omosh", "2-5-1987" }

};
//Am i supposed to call the second method from here.
personalDetailsContent( personArray [][] );

}

/**
* Demonstrates initializing and populating a multi-dimensional array
* in one statement
*/
private void personalDetailsContent() {

logger.debug( "personalDetailsContent()" );

String message = "Names:" +
personArray[0][0] + personArray[0][1] + "\tDOB: " +personArray[0] [2];
print( "personalDetails()", message );
message = "Names:" +
personArray[1][0] + personArray[1][1] + "\tDOB: " + personArray[1][2] ;
print( "personalDetails()", message );
message = "Names:" +
personArray[2][0] + personArray[2][1] +"\tDOB: " +personArray[2][2] ;
print( "personalDetails()", message );
message = "Names:" +
personArray[3][0] + personArray[3][1] +"\tDOB: " +personArray[3][2] ;
print( "personalDetails()", message );
message = "Names:" +
personArray[4][0] + personArray[4][1] +"\tDOB: " +personArray[4][2] ;
print( "personalDetails()", message );

}

Please someone help me how to do it.
