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); } ... }

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. https://www.sololearn.com/learn/Java/2220/ 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.
