java —— java基础语句

1. 字符串数组
   public class test {
   public static void main(String[] args) {
   String[][] str = {{“a”,“b”}, {“v”, “g”}, {“h”, “l”}};
   System.out.println(“a:”+str[1][1]);
   }
   }
   

2. 编写单个字母数组
   char[] matrix = new char[]{‘A’,‘B’,‘C’,‘E’,‘S’,‘F’,‘C’,‘S’,‘A’,‘D’,‘E’,‘E’};
   

3. 长度
   a.length

4. 调用函数
   // 用solution
   public static void main(String[] args) {
   char[] matrix = new char[]{‘A’,‘B’,‘C’,‘E’,‘S’,‘F’,‘C’,‘S’,‘A’,‘D’,‘E’,‘E’};
   char[] str = new char[]{‘A’,‘B’,‘C’,‘C’,‘E’,‘D’};
   test solution = new test();
   System.out.println("result "+solution.hasPath(matrix,3,4,str));
   }
