Since, the return type i.e. the class of the new instance is fixed; there's no need to pass it to the method. Instead, add a static
factory method to your Example
class as
public class Example<T> {
private T data;
static <T> Example<T> newTypedExample(Class<T> type) {
return new Example<T>();
}
public T getData() {
return data;
}
public void setData(T data) {
this.data = data;
}
}
Now, here's how you would create generic Example
instances.
// String
Example<String> strTypedExample = Example.newTypedExample(String.class);
strTypedExample.setData("String Data");
System.out.println(strTypedExample.getData()); // String Data
// Integer
Example<Integer> intTypedExample = Example.newTypedExample(Integer.class);
intTypedExample.setData(123);
System.out.println(intTypedExample.getData()); // 123
