NoClassDefFoundError NoSuchMethodError Note When executing a Java program, the JVM first loads the bytecode of the class to memory using a program called the class loader. If your program uses other classes, the class loader dynamically loads them just before they are needed. After a class is loaded, the JVM uses a program called bytecode verifier to check the validity of the bytecode and ensure that the bytecode does not violate Java’s security restrictions. Java enforces strict security to make sure that Java programs arriving from the network do not harm your computer.
