certainly! reading a text file line by line in java can be accomplished using various classes available in the java i/o package. one common way to read a text file is by using the `bufferedreader` class along with `filereader`. if you're looking to split each line using a specific delimiter (like commas, tabs, etc.), you can use the `string.split()` method.

tutorial: reading a text file line by line with a delimiter in java

#### step 1: set up your environment
make sure you have the java development kit (jdk) installed on your system. you can write your code in any ide (like intellij idea, eclipse, or even a simple text editor) and run it via command line or the ide.

#### step 2: create a sample text file
for demonstration purposes, create a text file named `sample.txt` with the following content:



each line in this file contains a person's first name, last name, and age, separated by commas.

#### step 3: write the java code

here's a simple java program that reads the `sample.txt` file line by line and splits each line using a comma as the delimiter.



#### step 4: explanation of the code

1. **import statements**: the program imports necessary classes.
`bufferedreader` is used for reading text from a character-input stream efficiently.
`filereader` is used to read the file.

2. **file path**: specify the path of the text file you want to read.

3. **try-with-resources**: this construct is used to ensure that the `bufferedreader` is closed automatically after use, preventing resource leaks.

4. **reading lines**: the program reads each line using `br.readline()`. it continues until there are no more lines to read (i.e., until `readline()` returns `null`).

5. **splitting the line**: each line is split into parts using the `split()` method of the `string` class. here, we're using a comma as the delimiter.

6. **accessing parts**: the parts of the split line are accessed using their index. the first part (index 0) is the first name, the second ( ...
