Enter the number 456
Entered number 456
Java program to print the number
Java program to print the number will create an idea of programming language with student. It will lead the learner to learn more programs in java.
How the system.out.print works and why it is needed
The print() method is employed. In Java, the System. out. println() function writes the value supplied as a parameter to it on the console screen and moves the cursor to the next line. After that, the entered integers are saved in the integer variable number.
The compiler will issue an InputMismatchException if you enter any character that is not an integer. Finally, the function println() is used to print the number on the standard output ( System. out ) – computer screen.
print(): In Java, the print() function is used to display text on the console. This method accepts this text as a parameter in the form of a String. This method outputs the text to the console while keeping the cursor at the conclusion of the text.
What is integer in java program
Only the binary value of an integer may be stored in it. Integer variables, like any other reference type, store references to Integer objects.
What is scanner in java and why it is needed?
It’s the simplest way to read input in a Java program, but it’s not particularly efficient if you’re looking for an input method for situations where time is a factor, such as competitive programming.
It implies importing all of Java’s classes and interfaces. Make the utilities in the util package available for usage within the current class or interface.
What is package in java programming and its uses?
A package is a namespace that groups together a collection of related classes and interfaces. Because software built in the Java programming language might have hundreds or thousands of distinct classes, it makes it logical to group similar classes and interfaces into packages to keep things organized.
