The term “subscript” is used because as a mathematical sequence, an array would be written with subscripts: Here 0, 1, 2, are the subscripts of variable x.Java provides another way to represent such types of variables. This is done by writing the indexes between two square brackets as:x [0],x[1],x[2],…
