To set up a string variable, you type the word String followed by a name for your variable. Note that there's an uppercase quotSquot for String. Again, a semicolon ends the line String first_name Assign a value to your new string variable by typing an equals sign. After the equals sign the text you want to store goes between two sets of double quotes

Using the Scanner class in Java allows us to read different types of inputs from the console and assign them to respective variables. This is particularly useful in interactive applications where user input is required.

Where type is one of Java's types such as int or String, and variableName is the name of the variable such as x or name. The equal sign is used to assign values to the variable. To create a variable that should store text, look at the following example

If the method is unable to find any string input, it throws the NoSuchElementException. If we close the scanner object and then try to take input, it throws the IllegalStateException. First, we need to create a Scanner class object which wraps around the system input. After that using the object we call the nextLine method to take String input.

I've googled around a bit, but can't seem to find an understandable explanation of how to use scanner to assign user input to a variable.
