分配双字符串数组

Question

我想创建一个新的String [] []数组，但日食给我一个错误：

public class CurriculumVitae { 

String[][] education = new String[2][6]; //throws error here and expects "{" but why? 
education[0][0] = "10/2012 − heute"; 
education[0][1] = "Studium der Informatik"; 
education[0][2] = "Johannes Gutenberg−Universit \\”at Mainz"; 
education[0][3] = ""; 
education[0][4] = ""; 
education[0][5] = ""; 
education[1][0] = "10/2005 − 5/2012"; 
education[1][1] = "Abitur"; 
education[1][2] = "Muppet-Gymnasium"; 
education[1][3] = "Note: 1,3"; 
education[1][4] = ""; 
education[1][5] = "";} 

Answer 1

你的代码必须在方法内部。例如：

public class CurriculumVitae { 

    public static void main(String[] args){ 
    String[][] education = new String[2][6]; 
    education[0][0] = "10/2012 − heute"; 
    education[0][1] = "Studium der Informatik"; 
    education[0][2] = "Johannes Gutenberg−Universit \\”at Mainz"; 
    education[0][3] = ""; 
    education[0][4] = ""; 
    education[0][5] = ""; 
    education[1][0] = "10/2005 − 5/2012"; 
    education[1][1] = "Abitur"; 
    education[1][2] = "Muppet-Gymnasium"; 
    education[1][3] = "Note: 1,3"; 
    education[1][4] = ""; 
    education[1][5] = ""; 
    } 
} 

Answer 2

您的声明没问题。

但是，您必须使用初始化块来分配array值。

只需在大括号内附上所有education[x][y]语句，或将它们移动到构造函数中。

• 初始化块例如

  public class CurriculumVitae { 
      String[][] education = new String[2][6]; 
      // initializer block 
      { 
       education[0][0] = "10/2012 − heute"; 
       education[0][1] = "Studium der Informatik"; 
      } 
  } 
  

• 构造示例

  public class CurriculumVitae { 
  
      String[][] education = new String[2][6]; 
      // constructor 
      public CurriculumVitae() 
      { 
       education[0][0] = "10/2012 − heute"; 
       education[0][1] = "Studium der Informatik"; 
      } 
  }
