How to read string from user in java?

Answer 1

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

Answer 2

you create a scanner. Scanner console = new Scanner(System.in); console ^ is just a variable. so you could write it Scanner whateveryouwant = new Scanner(System.in); and it would work. after creating a scanner Scanner console = new Scanner(System.in); you write console.next(); or if input is a number console.nextInt(); you can save user input like this- int a = console.next(); and call it back like this System.out.println(a); or System.out.println("your text here" + a + "more text if you want..."); so in a program it looks like this- Scanner console = new Scanner(System.in); String a; System.out.println("what is your name?"); a = console.nextInt(); System.out.println("hello " + a) out put looks like this what is your name? yournamehere hello yournamehere i hope that answered your question...

Answer 3

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();

}

}

Answer 4

if you compiling your code using cmd(Command line) after compiling you can run program ., the time you trying to run your code you can pass values to string array... ex

Compiling process-

javac Your_program_name.java

run program

java Your_program_name your_text

if u want to check your text .. please follow this code-

public class Your_program_name {

public static void main(String args[]) {

System.out.println(args[0]);

}}

Answer 5

public static void main (String args[]) throws IOException {

int abc = System.in.read();

}
