int college[][][];

I need 5 Students in one Department and 6 Students in another Department
Can we declares arrays like this. If so how?

int college[][][] = new int[3];
college[0] = new int[5];
college[1] = new int[6];
...
college[0][0] = new int[count_marks_dept1_student1];

If you really want to store this in a 3D-array you can do it the following way for 2 departments:
int college[][][] = new int[] {new int[5], new int[6]}
But it would be a far better approach to handle this in separate classes for Department and Student. Is there a special requirement why you need to handle this in arrays?

You can do this, but you should ask yourself if you shouldn't be using object-oriented programming techniques instead.
For example:
int departments = 5; // 5 departments
int[][][] college = new int[departments][][];
int students = 20; // 20 students in first department
college[0] = new int[students][];
int marks = 10; // 10 marks for first student in first department
college[0][0] = new int[marks];
college[0][0][0] = 3; // first mark for first student in first department
students = 17; // 17 students in second
college[1] = new int[students][];
// and so on...
Department, andStudents.
