NetBeans中的編譯錯誤

Question

任何想法爲什麼NetBeans 7標記中的此代碼與Deletion（刪除是客戶端軟件包中的類）一致爲錯誤？

package client; 

/** 
* 
* @author Arth 
*/ 
public class Client_Main 
{ 
    final String ORIGINAL_SEQUENCE =  "AAGCTGT"; 

     // Sample sequences demonstrating each type of DNA error 
     final String MUTATION_SEQUENCE =  "AATCTGT"; 
     final String TRANSPOSITION_SEQUENCE = "AAGTCGT"; 
     final String INSERTION_SEQUENCE =  "AAGACTG"; 
     final String DELETION_SEQUENCE =  "AGCTGTA"; 

     final String SEQUENCE_A =  "AAAAACCCCCGGGGGTTTTT"; 
     final String SEQUENCE_B =  "AAAACACCCCGGGGGTTTTT"; 

     public void check() 
     { 
      Deletion d("1","2"); 
     } 

} 

線：

Deletion d("1","2"); 

產生錯誤：

';' is expected

Answer 1

Deletion d = new Deletion("1","2"); 

Answer 2

此語法是非法的。如果你想創建一個新的對象，你應該要麼使用就地初始化：

Deletion d = new Deletion("1", "2"); 

或聲明之後初始化：

Deletion d; 
d = new Deletion("1", "2"); 

Answer 3

你真的沒有給予足夠的信息，但嘗試

Deletion d = new Deletion("1", "2"); 

Answer 4

或者，如果您不是分配d，您可以直接簡單地調用該對象，如下所示：

new Deletion("1", "2");
