What are the characteristics of java generic methods

1. Description

The relationship between public and return value is very important and can be understood as a universal method. Only the described methods are generic methods, and the member methods used in generic classes are not generic methods.

This method will use generic T, and generic T can be used at this time. Just like the definition of generics, T here can be written as any identifier. Common parameters such as T, E, K, V, etc. are usually used to represent generics.

2. Example

class DataHolder{     
T item;        
  public void setData(T t) {  
      this.item=t;   
  }      
  public T getData() {   
     return this.item;  
   }        
     /**      * 泛型方法      * @param e      */   
   publicvoid PrinterInfo(E e) {    
       System.out.println(e); 
    } 
}
