java 反射设置值

public static void main(String[] args){
    String setMethodName = "setinstitution";
    String currCellString = "pending";
   
    Class c;
try {
c = Class.forName("User");

Object o = c.newInstance();
Method[] methods = c.getMethods();
for (Method method : methods) {
String methodName = method.getName().toLowerCase();
System.out.println("++The current Method name is: " + methodName);

if (methodName.equals(setMethodName)){    
method.invoke(o, currCellString);
System.out.println("-------Sucessfully " + setMethodName);
break;
}     
}
System.out.println("@@@" + ((User)o).getInstitution());
} catch (ClassNotFoundException e) {
e.printStackTrace();
    } catch (InstantiationException e) {
    e.printStackTrace();
    } catch (IllegalAccessException e) {
    e.printStackTrace();
    } catch (InvocationTargetException e) {
    e.printStackTrace();
    }
    }

另一种高效率的方法
String currCellString = "pending";
   
    Class c = Class.forName("test");
Object o = c.newInstance();
Method method = c.getMethod("setInstitution", String.class);
method.invoke(o, currCellString);
System.out.println("@@@" + ((User)o).getInstitution());
