Java tuitorial - basic concepts, getting user input - drag and drop question

Question

Greetings,

In the Java tuitorial - basic concepts, getting user input - drag and drop question, I dont understand the answer and I wanted to know if the word 'next' is a special Java operator like 'scanner' is?

Would like to understand why 'nextLine' was the correct choice?

Kind regards

BcE

Answer 1

Drag and drop to create a component that logs the value of the "name" state variable when it gets updated.

Answer
class Test extends React.Component {
state = {
name: "Test"
}
componentDidUpdate() {
console.log
(this.state.name);
}
...
}

Answer 2

Both next() and nextLine() are methods of the Scanner class. If you take a look at the example given in the tutorial (right after listing some methods included in the scanner class), it uses nextLine() to get input from the user.

Next() stops getting input if the user enters a space while nextLine() only stops when the carriage return/enter key is pressed by the user.

Found it!

Read a complete line - nextLine()
Read a word - next()

Thank you
