What is the purpose of "new" in Java?

Hey guys,

What is the purpose of using "new" when we instantiate a variable? I can't seem to find any resources online that can explain it to me in a succinct way... any help would be greatly appreciated! :)

The new keyword is a Java operator that creates the object. For more info follow this official oracle doc : Creating Objects : The Java™ Tutorials

Thank you so much for that :) However I am still confused with this example:

System.out.println("Enter cost of meal in US Dollars: "); Scanner keyboard = new Scanner(System.in); double answer = keyboard.nextDouble();

Why is scanner an object when it is simply asking for the cost of meal?

Thanks :)

System.out.println("Enter cost of meal in US Dollars: "); // it is print the text in paretesis

Scanner keyboard = new Scanner(System.in); // this object is for receive input "System.in"

double answer = keyboard.nextDouble(); // nextDouble is a method of Sanner object that will save you input ins answer in double format
