給出一個字符串數組的二進制值

Question

我想給一個字符串數組的二進制值例如。

String list_command[]= {"movie", "audio", "games", "current_time", "city", "city"}; 

會像

list_command = 000,001,010,011,100,101 

Answer 1

創建二進制數組

public static byte[][] toBinary(String... strs) { 
    byte[][] value = new byte[strs.length][]; 

    for(int i=0; i<strs.length; i++) { 
     value[i] = strs[i].getBytes(); 
    } 

    return value; 
} 

生成字符串數組

public static String[] toStrings(byte[][] bytes) { 
    String[] value = new String[bytes.length]; 

    for(int i=0; i<bytes.length; i++) { 
     value[i] = new String(bytes[i]); 
    } 

    return value; 
} 

打印值：源（Convert A String (like testing123) To Binary In Java）

public static void print(byte[][] bytes) { 
    for(byte[] bArray : bytes) { 
     StringBuilder binary = new StringBuilder(); 

     for (byte b : bArray) 
      { 
      int val = b; 
      for (int i = 0; i < 8; i++) 
      { 
       binary.append((val & 128) == 0 ? 0 : 1); 
       val <<= 1; 
      } 
      binary.append(' '); 
      } 

     System.out.println(binary.toString()); 
    } 
} 

主要

你希望有人編寫

public static void main(String... args) { 
    print(toBinary("Hello", "World")); 
}

你可以嘗試使用Dictionary。我不知道你想什麼，你的鑰匙/值，但如果你想查找由您在list_command[]有一個字符串，你可以嘗試這樣的事：

Dictionary<string, string> commandsToBinary = new Dictionary<string,string>(); 

for(int i = 0; i < list_command.Length; i++){ 
    string binaryCommand = Convert.ToString(i,2); // Get the binary representation of `i` as a string. 
    commandsToBinary.Add(command, binaryCommand); //switch command & binaryCommand to have the binary strings as your keys. 
}
