如何基于Java中的数字将字符串放入数组中的特定位置？

Question

How would I put a string into an array in a specific spot based on a number?

public Student(String firstName, String lastName, String studentNumber, int grade){
    courseTimeTable = new String[] {"Block " + courseBlock + ": " + course, "Block " + courseBlock + ": " + course};
}

public void setCourse(int block, String courseCode) {
    course = courseCode;
    courseBlock = block;
}

So how would I put the "course" into the "courseTimeTable" array based on the "courseBlock"

Answer 1

You will need to know the maximum size of courseTimeTable first.

Then you can do:

 courseTimeTable = new String[<maximumSize>];
 courseTimeTable[courseBlock] = ...;
