从文本文件中的一行读取特定数据到相应的 arrays，在 Java

Question

This is in a text file

After each comma on the line, it's a different piece of data, eg

the first data is first name, then surname, then contact number, then address, then college, then college id, then course, then specialization

I need to write a java program that will read the text file and for each line, and for each piece of data, will store the information into respective arrays in the program, for example, all the “first names” read will be stored in an array called “first name” and so on.

This was easy to for me to write in python using line.split(“,”) but java is totally different for me to understand

Answer 1

Yes you can also achieve this in java using split method by splitting the each line by separate in your case it is comma and you will get string array.Then iterate over the array and map your keys.

Consider below example

String line = "Amit, 29"; String []values = line.split(","); String name = values[0]; String age = values[1];
