how to iterate value from one array and save it to another array

public static void main(String[] args) {
		TestSection ts = new TestSection();
		Section s = new Section();
		String[] str = new String[] { "Jack:90:92:90:90:90",
				"Shazz:88:45:76:60:44", "Nazz:74:44:56:64:52" };
		s = ts.makeSections(str);
		System.out.println(s.nameofA());
	}

	public Section makeSections(String[] studentsData) {
		Section sc = new Section();
		sc.student = new Student[studentsData.length];
		String[] studentsDta = new String[3];
		for (int i = 0; i < studentsData.length; i++) {

			studentsDta = studentsData[i].split(":");
			sc.student[i] = new Student();
			sc.student[i].name = studentsDta[0];
			sc.student[i].marks = studentsDta[];

		}

		return sc;
