Public Class not require

[Shankar sanjay]

Hi,

A Class did not declare Public then i can run both Class in the same file..But in SCJP Cathy Seira Book (1.6)
mentioned (page number 11) that in a source file there should be one Public. If i didnt not declare any public i can access any class from command prompt.

Code :
-----
package com;

class Test {

public static void main(String[] args) {
// TODO Auto-generated method stub
int $x = 10;
System.out.println(/* printing x vlaue */$x);

}
}

class Test1 {
public static void main(String[] args) {
// TODO Auto-generated method stub
int $x = 20;
System.out.println(/* printing x vlaue */$x);

}
}

Output:
--------
D:\Eclipse\Workspace\Test1\src>javac com/Test1.java
error: cannot read: com/Test1.java
1 error

D:\Eclipse\Workspace\Test1\src>javac com/Test.java

D:\Eclipse\Workspace\Test1\src>java com/Test
10

D:\Eclipse\Workspace\Test1\src>java com/Test1
20

You do know that in Windows you must use \ instead of / between parts of a path, don't you?

As Rob said, try this:

javac com\Test1.java

Note: Use backslash \ and not forward slash / if you are doing this on Windows.

A Java program is a collection of one or more classes, with one of them containing the program's execution starting point. A Java source
file can contain more than one class definition. The Java 2 SDK enforces the rule that at the most one class in the source file has public
accessibility. The name of the source file is comprised of the name of this public class with .java as extension. Each class definition in a
source file is compiled into a separate class file, containing Java byte code.

try this

class publicTest {

/**
* @param args
*/
public static void main(String[] args) {
// TODO Auto-generated method stub

System.out.println("hello");

}

}
class publicTest1{

public static void main(String[] args) {
// TODO Auto-generated method stub

System.out.println("hello");

}


}

save file with name publicTest in eclipse & try to run . it will run fine.
