In this example, we created a. Web here is the syntax for the java scanner class: Web in java, we can use java.util.scanner to get user input from console. Web scanner sc = new scanner (system.in); Int n = reader.nextint ();.
The preceding sentence builds a function object () { [native code] }. Web it is the simplest method for a java program to read input. Web it means it is going to read from the standard input stream of the program. The easy way (and short) if you use java 7: Web in java, you can simply use system.out.println ();
It will put all file. Web sometimes, the developers also need to take the multiple inputs in a single line. Int n = reader.nextint ();. // reading from system.in system.out.println (enter a number: Web read input by using system.in in java using the system.in in a java code is easy;
