Compiler Vs Interpreter Java code is considered to be both compiled & interpreted. During the build process, the Java source code is first compiled into bytecode. The generated bytecode is then interpreted by the JVM for execution. Java applications are called WORA (Write Once Run Anywhere), ...
public interface JavaCompiler extends Tool, OptionChecker 用于从程序中调用Java编程语言编译器的接口。 编译器可能在编译期间生成诊断(例如,错误消息)。 如果提供了诊断侦听器,则会将诊断程序提供给侦听器。 如果未提供侦听器,则诊断将以未指定的格式进行格式化,并写入默认输出,即System.err除非另有说明。 即使提供...
