Java Method getGenericReturnType() Method

The getGenericReturnType() method of Method class returns a Type object that represents the formal return type of the method represented by this Method object. If the return type is a parameterized type, the Type object returned must accurately reflect the actual type parameters used in the source code.

Syntax

Parameter

No parameter is passed.

Returns

a Type object that represents the formal return type of the underlying method

Throws

GenericSignatureFormatError

TypeNotPresentException

MalformedParameterizedTypeException

Example 1

//import statement
import java.lang.reflect.Method;
import java.lang.reflect.Type;
public class ReflectMethodgetGenericReturnTypeExample1 {
   public static void main(String[] args) {
      Method[] mthd = SampleX.class.getMethods();
      Type rType = mthd[0].getGenericReturnType();
      System.out.println(rType);
   }
}
class SampleX {
   private String Field;
   public String getSampleField() {
      return Field;
   }
   public void setSampleField(String Field) {
      this.Field = Field; 
   } 
}
