If you’re new to Java programming, getting started can be a bit overwhelming. But don’t worry – there are plenty of resources available to help you get up to speed quickly. Here are a few places to start:
- The Java Tutorials: The official Java tutorials from Oracle are a great place to start learning the language. They cover everything from the basics of writing Java code to more advanced topics like creating graphical user interfaces.
- The Java Forums: The Java Forums are a great place to ask questions and get help from other Java programmers. You can also search the forums for answers to common questions.
- The Java Developers Almanac: The Java Developers Almanac is a great reference for Java programming. It includes topics like class libraries, data types, and common programming tasks.
These are just a few of the many resources available to help you learn Java programming. With a little effort, you’ll be writing Java code in no time.
what does % mean in java
The “%” symbol in Java is called the modulo operator. The modulo operator is used to find the remainder of a division operation. For example, if you divide 10 by 3, the remainder would be 1.
The modulo operator would return this value. Additionally, the modulo operator can be used as a shortcut for finding odd and even numbers. If a number is divided by 2 and the remainder is 0, then the number is even. If the remainder is 1, then the number is odd.
How do you use Scanner in Java
Scanner is a class in java.util package used for obtaining input of primitives like int, long etc. and strings. It is the easiest way to read input in a Java program. It is overloaded for all primitive types.
How do you print in Java
System.out.println() is a static method of PrintStream class used to print data in Java, inside the brackets, we have to pass the data which we want to print. It prints the data on the standard output device i.e console. This method always adds a new line after printing the data.
System.out.print() is a static method of PrintStream class used to print data in Java. It is similar to println() method but it doesn’t add a new line after printing the data.
What is the use of ArrayList in Java
An ArrayList is a resizable-array implementation of the Java List interface. It implements all optional list operations, and permits all elements, including null. In addition to implementing the List interface, this class provides methods to manipulate the size of the array that is used internally to store the list. (This class is roughly equivalent to Vector, except that it is unsynchronized.)
The size, isEmpty, get, set, iterator, and listIterator operations run in constant time. The add operation runs in amortized constant time, that is, adding n elements requires O(n) time. All of the other operations run in linear time (roughly speaking). The constant factor is low compared to that for the LinkedList implementation.
