Learn Java from Scratch - A Beginner's Guide - Step 09 - Printing Output to Console with Java - Exercise Solutions

This video tutorial covers the basics of using the 'System.out.println' method in Java to print strings and expressions. It starts with printing 'Hello World' using string literals, then moves on to printing expressions like '5 into 3' as strings. The tutorial also demonstrates calculating and printing the multiplication table of 5 and the number of seconds in a day. Finally, it reviews the syntax and parameters of methods in Java, emphasizing the difference between string literals and expressions.

What is necessary to print a text like 'Hello World' exactly as it is using System.out.println?

• Use a character literal

• Use a boolean literal

• Use a numeric literal

• Use a string literal

How can you print the expression '5 into 3' as a string using System.out.println?

• By using a string literal with spaces

• By using a boolean expression

• By using a numeric calculation

• By using a character array

What is the result of printing the expression 5 * 3 without quotes in System.out.println?

• The string '5 * 3'

• The calculated value 15

• An error message

• The string '15'

How should you print the number of seconds in a day using System.out.println?

• By using a character literal

• By using a string literal

• By using a direct expression

• By using a boolean value

What is the role of parameters in the System.out.println method?

• They determine the method's visibility

• They are the values passed to the method

• They specify the method's name

• They define the method's return type
