1. Parallel arrays can be achieved by using two arrays in which corresponding elements are related.2. In this example, the parallel arrays are both full and the loops use the instance variable length. 3. String [] name = new String[50]int [] age = new int [50]int [] security = new int [50]String searchPerson;int correspondingAge = -1, correspondingSecurity = -1searchName = …for (int i = 0, i<name.length; i ++) if (searchName.equal (name[i]))correspondingAge = age [i]correpondingSecurity = security [i]break;}4.5.       array should contain the exponent and the other array should contain 2 raised to that power.
