everything seems so simple in java except the I/O stream. I have my program due in 2days and ive done everything but the I/O, people say it takes forever? so like whats the fastest and easiest way to input into a string or char? and whats the easiest way to output the same? like the basic and most simplest way ? Thanks...

Scanner scan = new Scanner(System.in); for input
System.out.print(whatever}; is the equivalent of cout <<

How does this have anything to do with C++ to Java?

As for your question, the Scanner class is commonly used for input and to output in your console...you just use System.out.print()...

Scanner in = new Scanner(System.in);
String userInput = in.nextLine();
System.out.println("Your input was: " + userInput);

Note: you must import the Scanner class from java.util package

oh coz iam from C++ and just switched to java.sry abt that... so i gotta do import java.util at the top? and thats it ? people talked about adding classes and classes to do this kinda stuff? whats that abt ?
PS: Garbage collection FTW

// imports the entire util package...
// * means ALL
import java.util.*;
// imports just the Scanner class from the util package
import java.util.Scanner;

does the scanner also output? scanner.out?

No use System.out.print() or System.out.println(); witha LineFeed as
bcranger showed you

Scanner in = new Scanner(System.in);
String userInput = in.nextLine();
System.out.println("Your input was: " + userInput);

Hi, I believe you might want to read about the difference in System.out.println(), System.out.print(), etc. as each of them serve a different purpose and also something like:

Scanner sc = new Scanner(System.in);
int temp = sc.nextInt();
double temp2 = sc.nextDouble();

nextInt() and nextDouble is used for different purpose.
