Therefore, Java is both a compiled and interpreted language.
Compilation involves scanning an entire source code and translating it into machine code at once.
An interpreter, on the other hand, convertssource codeinto machine code one line at a time.
During compilation, the compiler creates a list of all identifiers used in the program.
When a Java program is being compiled, errors may arise during the compilation process.
Such errors are known as compilation errors or compile-time errors.
Compilation errors prevent the Java compiler from successfully generating a programs bytecode.
Compilation errors prevent your program from being compiled.
Such errors may be due to syntax, semantic or structural errors in the source code.
An example of a compilation error is the Cannot Find Symbol Error.
A cannot find symbol error can lead to failed compilation.
In the example, the variableeven_numberand the method nameaddNumberswere misspelled and they used the wrong cases.
In our case, the variablesyandnumwere used before being declared.
Correct this error by using them after their declaration.
The variablexwas used outside the scope it was declared in.
To create an instance of a class in Java, you better use the new keyword.
Importing the scanner class makes it available for use as shown.
In the code that generated an error, the class that was imported wasDates.
However, there is no inbuilt class calledDates.
The correct name isDate.
Therefore, no bytecode will be generated to be used in executing the program.
Additionally, the overall source code quality is affected due to bugs in the source code.
Luckily, it is also a very easy error to avoid.
Cannot find symbol error results from the wrong use of identifiers.
