Question

我想创建一个新的String [] []数组，但是eclipse给了我一个错误：

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

您的声明没问题。

但是，您必须使用初始化程序块来分配array值。

只需将所有education[x][y]语句括在花括号中，或将它们移动到构造函数中。

初始化程序块示例

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

构造函数示例

public class CurriculumVitae {

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

Answer 2

你的代码必须在方法内。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] = "";
  }
}

分配双字符串数组
