In one of my classes i have put below lines of code to call the preOTPOperations of BLH class
Class<?> clazz = Class.forName("com.test.BLH");
Object obj = clazz.newInstance();
Class<?>[] paramTypes = new Class[4];
paramTypes[0]=String.class;
paramTypes[1]=String.class;
paramTypes[2]=Integer.class;
paramTypes[3]=COConfig.class;
Method m = clazz.getDeclaredMethod("preOTPOperations", paramTypes);
String responseMessage = (String) m.invoke(obj, new Object[]{cardnumber, null, bankId, myConfig});
But, i get java.lang.NoSuchMethodException, when i try to invoke preOTPOperations method of BLH as above using invoke().
In BLH class i have preOTPOperations as below.
public String preOTPOperations(String cardnumber, String mobileNumber, int bankid, COConfig coConfig){
//some code goes here
}
Not sure why i am getting NoSuchMethodException in spite of having preOTPOperations in BLH class with public access specifier. Someone kindly suggest the solution. Am i missing something? Thanks in advance!
You need to change Integer.class to int.class. Integer and int are not the same types, and the method isn't found because you're specifying the wrong type.
