I get this Error

Part3 - Find the students with highest GPA

------------------------------------------------

Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: Index 3 out of bounds for length 3

at StudentShuffle.getStudentsWithPerfectGPA(StudentShuffle.java:113)

HERE IS THE CODE, PLEASE FIX the problem WITHOUT CHANGING A LOT OF CODE.

Student.java

Use the this keyword. } public double getGPA() { // TO-DO: return this.gpa return this.gpa; } public String getName() { // TO-DO: return this.name return this.name; } // toString method: this is a handy way to specify what you want it to look like when you // print a Student object. Without this, printing a student using System.out.println(student) // will print a memory address. The toString method is called implicitly (you don't have to // call it explicitly when you print) public String toString() { return "[" + name + ", " + major + ", " + gpa + "]"; } }
