회사서 Class를 조사할 일이 있는데 reflect를 까먹어서 한동안 googling 해서 다시 학습…
java.lang.String의 method를 출력하는 루틴의 골자만 요약하면….
import java.lang.reflect.*;
public class ClassExam{
public void printClassInfo(String className){
try{
Class a = this.getClass().getClassLoader().loadClass(className);
Method[] methods = a.getDeclaredMethods();
for(int i=0; i<methods.length; i++){
System.out.println(methods[i].toString());
}
}catch(Exception e){
}
}
public static void main(String[] args){
ClassExam a = new ClassExam();
a.printClassInfo("java.lang.String");
}
}
public class ClassExam{
public void printClassInfo(String className){
try{
Class a = this.getClass().getClassLoader().loadClass(className);
Method[] methods = a.getDeclaredMethods();
for(int i=0; i<methods.length; i++){
System.out.println(methods[i].toString());
}
}catch(Exception e){
}
}
public static void main(String[] args){
ClassExam a = new ClassExam();
a.printClassInfo("java.lang.String");
}
}
