Learn Java from Scratch - A Beginner's Guide - Step 09 - Exploring New Java API - Files - readString and writeString Met

The video tutorial introduces file-related methods introduced in JDK 11, specifically 'readString' and 'writeString'. It demonstrates creating a Java class to read and write text files using these methods. The tutorial covers creating a sample text file, reading its content, modifying the content, and writing it to a new file. The ease of using these methods for file operations is highlighted, along with their default UTF-8 encoding.

What are the two file-related methods introduced in JDK 11?

• readText and writeText

• readFile and writeFile

• readData and writeData

• readString and writeString

Where is the sample text file created in the tutorial?

• In the src folder

• In the resources folder

• In the bin folder

• In the lib folder

What is the purpose of the 'path' variable in the file reading process?

• To store the file content

• To specify the file location

• To handle exceptions

• To execute the main method

Which method is used to read the content of a file in JDK 11?

• Files.readData

• Files.readText

• Files.readFile

• ArrayIndexOutOfBoundsException

• FileNotFoundException

How is the file content modified before writing to a new file?

• By removing all spaces

• By converting to uppercase
