Trying to get a string from user input

I trying to get this code to get user input instead of reading from a hardcoded array. I'm getting compile errors while trying to get user input. Where did I go wrong? Here's some of the code:

Java Code:

// BubbleSort Java
// compile with:  javac BubbleSort.java
// run with: java BubbleSort

import java.util.Arrays;
import java.io.*;
import java.util.Scanner;

public class BubbleSort {
    
  public static void main(String args[]) {
        String name;
    int swapHolder;
    int sizeOfArray = 0; 
    int pass = 1; // 
    int[] myArray;  
        //**write to array from file -- one int per line**
        TextIO.put("Enter the filename from which you would like to read from: ");
        name = TextIO.getln();
        BufferedReader br = new BufferedReader(new FileReader(name));
    int num;
    while ((line = br.readLine()) != null) {
       myArray[sizeOfArray] = num;
       sizeOfArray ++;   
    }
    br.close();

The errors:



BubbleSort.java:18: error: cannot find symbol



TextIO.put("Enter the filename from which you would like to read from: ");
