What would be the best way to merge two arrays of different lengths together so they are evenly distributed in the new array?

Say I have the following arrays

 String[] array1 = new String[7];
 String[] array2 = new String[2];
 String[] mergedArray = new String[array1.length + array2.length];

I would want mergedArray to have the following elements

array1 array1 array1 array2 array1 array1 array1 array2 array1

but if I were to change the size of the arrays to

 String[] array1 = new String[5];
 String[] array2 = new String[3];
 String[] mergedArray = new String[array1.length + array2.length];

then I would want it to be

array1 array2 array1 array2 array1 array2 array1 array1

basically if it can be helped each array2 element shouldn't be touching each other; exception if array2 has a size larger than array1.
