Java program to give input of a string and display it?
import java.util.*; public class Example { public static void main(String[] args) { Scanner in = new Scanner(System.in); System.out.println("Please enter a string:"); String input = in.next(); System.out.println("The String you entered is: " + input); } }
What happens when one string is appended to the end of another in Java?
This is called "concatenation", and pretty much just smashes the two Strings together. For example: import java.util.*; public class Example { public static void main(String[] args) { Scanner in = new Scanner(System.in); System.out.println("Please enter a string: "); String input = in.next(); System.out.println("Please enter another string: "); String input2 = in.next(); String together = input + input2; System.out.println("The strings concatenated yields: " + together); } } OUTPUT: Please enter a string: Hello Please enter another string: Goodbye The strings concatenated yields: HelloGoodbye As well, you can use String.nextLine() to get more than one word per string: import java.util.*; public class Example { public static void main(String[] args) { Scanner in = new Scanner(System.in); System.out.println("Please enter a string: "); String input = in.nextLine(); System.out.println("Please enter another string: "); String input2 = in.nextLine(); String together = input + input2; System.out.println("The strings concatenated yields: " + together); } }
What is class variable?
Class Variables or Instances variables are variables that are declared inside a class and are available for the whole class. They are available for all instances of that class and are not specific to any method. Ex: public class Test { private String name = "Rocky"; } Here name is a class variable.
How to read string from user in java?
There are many ways to input data from the keyboard, but the most convenient is the use of the Scanner class. By declaring the Scanner class's input as System.in, it pulls data from the keyboard (default system input). A simple example of taking data from the keyboard: For instance if I had typed ( Hello my name is William, I like cheese. ) The following code would process it. Scanner scan = new Scanner(System.in); String mySentence = scan.nextLine(); System.out.println(mySentence); // it would display what I had typed in. Other methods of the Scanner include: next(); // gets the next token from input using a delimiter (the default is white space) nextInt(); // returns the integer value of a number inputed nextDouble(); // returns the double inputed

What is difference between String str and String s equals new String?
Btw, this is a C++ question. in 'String str', str is an object and most probabily (based on most String implementations) we can use str = "my name"; int len = str.length(); String s = new String; <== this is something wrong. it should be String *s = new String; here 's' is a pointer and the object is allocated/instanciated by 'new' operator you can use it *s = "my name" int len = s->length()
