Compile time error is any type of error that prevent a java program compile like a syntax error, a class not found, a bad file name for the defined class, a possible loss of precision when you are mixing different java data types and so on.
A runtime error means an error which happens, while the program is running. To deal with this kind of errors java define Exceptions. Exceptions are objects represents an abnormal condition in the flow of the program. It can be either checked or unchecked.
'Compile time error' is when the compiler (javac) detects an error in your program.
Very simply, Java compile time is when Java is in the process of compiling source code, and run time is when Java is actually executing your program.
javac compiler can be used for compile the program and java can be used for run the program.
If you want to compile a java program the name of that source code must end with extension .java
use the javac keyword to compile a Java program.javac filename.java is the syntax to compile a java file.
Error: Any departure from the expected behavior of the system or program, which stops the working of the system is an error. Exception:Any error or problem which one can handle and continue to work normally. Note that in Java a compile time error is normally called an "error," while a runtime error is called an "exception." Errors don't have subclasses while exception has two subclasses, they are compile time exception or checked exception (ClassNotFound Exception, IOException, SQLException etc.) and runtime or unchecked exception(ArrayIndexOutOfBounds Exception, NumberFormat Exception).
Runtime Error Cannot be Rectified but Runtime Exception can.
javac somefile.java ^that will compile java somefile.java ^that will execute
When you compile a Java source file (.java) you get a Java bytecode file (.class). The bytecode in these .class files can be executed by the Java Virtual Machine.
there is no difference between java2 and java. its same. http://javacodespot.blogspot.com/
You compile it.You compile it.You compile it.You compile it.
One can run and compile a Java applet program by agreeing to the terms and downloading it. It is possible to get a compiler online that will compile and run Java programs.
