What does >= mean in Java?

Checks if the value of left operand is less than the value of right operand, if yes then condition becomes true. (A < B) is true. >= (greater than or equal to) Checks if the value of left operand is greater than or equal to the value of right operand, if yes then condition becomes true.

What is a scanner in Java?

Scanner is a class in java. util package used for obtaining the input of the primitive types like int, double, etc. and strings. It is the easiest way to read input in a Java program, though not very efficient if you want an input method for scenarios where time is a constraint like in competitive programming.

What is the difference between this () and super ()?

Difference between super() and this() in java Program No. this keyword mainly represents the current instance of a class. On other hand super keyword represents the current instance of a parent class. … super keyword used to call default constructor of the parent class.

They are called so because their values are instance specific and are not shared among instances.

What is the difference between print () and println ()?

The println(“…”) method prints the string “…” and moves the cursor to a new line. The print(“…”) method instead prints just the string “…”, but does not move the cursor to a new line. Hence, subsequent printing instructions will print on the same line.

You can use % just as you might use any other more common operator like + or – . Perhaps surprisingly the remainder operator can be used with floating point values as well.

How do you cast in Java?

In Java, there are two types of casting:Widening Casting (automatically) – converting a smaller type to a larger type size. byte -> short -> char -> int -> long -> float -> double.Narrowing Casting (manually) – converting a larger type to a smaller size type. double -> float -> long -> int -> char -> short -> byte.
