Java泛型类与泛型方法的定义详解

public class Base<T> {
  T m;
  Base(T t) {
    m = t;
  }
  public T getM(){
    return m;
  }
  public void print() {
    System.out.println("base print ： " + m);
  }
  public static void main(String[] args) {
    Base<String> base=new Base<String>("base class is general");
    System.out.println(base.getM());
    base.print();
  }
}

public class GeneralMethod {
   public static <U> void print(U[] list) {
     System.out.println();
     for (int i = 0; i < list.length; i++) {
      System.out.print(" " + list[i]);
     }
     System.out.println();
   }
   public static void main(String[] args) {
     String a[]={"a","b","c","d","e"};
     Character b[]={'1','2','3','4','5'};
     Integer c[]={1,2,3,4,5};
     GeneralMethod.print(a);
     GeneralMethod.print(b);
     GeneralMethod.print(c);
   }
