Java Create a StringReader

To create a StringReader in Java, you can use the following code:

StringReader reader = new StringReader("Hello, World!");

This creates a new StringReader called reader that reads from the string "Hello, World!". The StringReader is a class that allows you to read a string as if it were a stream of characters.

You can then use the read method of the StringReader to read the characters of the string, like this:

int c = reader.read(); // reads the first character of the string

The read method returns the ASCII value of the character that it reads. To convert the value to a char, you can use a type cast, like this:

char ch = (char) reader.read(); // reads the first character of the string and converts it to a char

It is important to remember to close the StringReader when you are finished reading from it, to release any resources that it is using. You can do this using the close method, like this:

reader.close();
