Understanding Compile-Time vs. Run-Time Errors In Java, there are two major types of errors:compile-time errors and run-time errors. Compile-time errorsare those preventing the code from being compiled. Such errors can be either a syntax error or an error in the structure of the application...
Compile time errors in Java are a source of great frustration to developers, especially as they try to learn the language. Compile time error messages are notoriously unclear, and troubleshooting such errors can be overwhelming. To help alleviate the frustrations that compile time error often evoke,...

Two run-time constants are printed in our example, a user-defined value and a randomly generated value. 5. Static Code Optimization The Java compiler staticallyoptimizesall compile-time constants during the compilation process. Therefore,the compiler replaces all compile-time constant references with ...
2. Example of Error Let’s imagine we have the following class DemoClass: package com.baeldung; public class DemoClass { // fields and methods } Now, let’s try to compile the DemoClass using the javac command: javac DemoClass The above command will give an error: error: Class name...
application itself and cannot be constructed by the application itself. A number of these components exist specifically for the purposes of providing functionality in dev mode, for example, the source mapper allows the Play error handlers to render the source code of the place that an exception ...

3. Place the required extra libraries, ant-contrib.jar and junit.jar, in a separate directory—for example, "C:\connectorj-extralibs". > ant-contrib.jar and junit.jar and hibernate-core-4.2.12.Final.jar $ cp ant-contrib-1.0b3.jar mysql-connector-java-5.1.30/src/lib/ant-contrib.jar ...
Example public class TestClass { public static void main(String[] args) { int x = 2; int y = 4; sum = x + y ; System.out.println(sum); } } output TestClass.java:10: error: cannot find symbol sum = x + y ; symbol: variable sum location: class TestClass TestClass.java:...
For example, in Java® all names that reference methods, types, and fields must be defined in the system at the time a method is compiled. To allow Java® to be compiled incrementally, reference checking of such similar names are deferred as necessary until runtime, on demand by the ...
