Some keywords

[guisome]

Can any of you explain a bit these lines or just point out a tutorial.

/**
*Output:
28
*/

import java.util.Scanner;
public class MainClass {
public static void main(String args[]) {
String instr = "Name: Joe Age: 28 ID: 77";

Scanner conin = new Scanner(instr);

conin.findInLine("Age:"); // find Age

if (conin.hasNext())
System.out.println(conin.next());
else
System.out.println("Error!");

}
}


Scanner: findInLine(String str) : Scanner*«*java.util*«*Java by API

What's the "conin" variable? What's the funcition of the "new" with "Scanner"? And the "(instr)" ? the part "conin.findInLine" is to make that specific API uses the conin's stored information? I don't mind reading tutorials if you want to point out some.

Scanner is a class in the Java API since ver 1.5. It is a convenience class that allows you to read input.

The new keyword you should have learnt in class. It is used anytime you want to create a new instance of a class.

Passing instr to the Scanner constructor simply means that the String value in the instr variable is what the Scanner object will read.

findInLine is a method of the Scanner class. Go to the Java API and read what it does.

Thanks for answering this thread.

Yes I got, I was just a bit confused regarding both "Scanner", but after reading a tutorial I realized it's a class variable not a comum type.
