        animalYOB2, animalYOB3, and animalYOB4 and that Name1 goes with 
        YOB1, etc.  Write the Java code to output these values in a table.  
        The table should have three columns with the first column being 
        a number (1, 2, 3,  and 4), the second column being Name# and the 
        third column being YOB#.  The table should have 5 rows where the 
        first row is titles of “”, “Name”, and “Born In”.  The first 
        column should be 3 characters wide, the second column should be 
        20 chars wide, and the last column should be 10 chars wide.
