文字列を「N」の等しい部分に分割するJavaプログラム

この記事では、文字列を「N」個の等しい部分に分割する方法を理解します。文字列は、1つ以上の文字を含み、二重引用符（“”）で囲まれたデータ型です。

Input string: Java Program is fun!

必要な出力は −

The length of the string is: 20
4 equal parts of given string are

fun!

アルゴリズム

Step 1 - START
Step 2 - Declare a string namely input_string, two integers namely string_length and N.
Step 3 - Define the values.
Step 4 - Initiatize a temporary variable to 0.
Step 5 - Compute the parts in the string by dividing the length of the string by ‘N’.
Step 6 - If the string is not divisible by N, display a relevant message. Given that the string length is divisible by N, iterate through the string.
Step 7 - Fetch the substring within the range of string length and N in every iteration. Assign this value to a variable.
Step 8 - Increment the temporary variable after every iteration.
Step 9 - Display the N parts of the string on the console by iterating over the split parts of the string.
Step 10 - Stop

例1

ここでは、「main」関数の下ですべての操作をバインドします。

public class Demo {
   public static void main(String[] args) {
      String input_string = "Java Program is fun!";
      System.out.println("The string is defined as: " +input_string);
      int string_length = input_string.length();
      System.out.println("The length of the string is: " +string_length);
      int N = 4;
      int temp = 0, string_parts = string_length/N;
      String[] equalStr = new String [N];
      if(string_length % N != 0) {
      System.out.println("The string cannot be divided int "+ N +" parts.");
      } else {
         for(int i = 0; i < string_length; i = i+string_parts) {
            String part = input_string.substring(i, i+string_parts);
            equalStr[temp] = part;
            temp++;
         }
         System.out.println(N + " equal parts of given string are ");
         for(int i = 0; i < equalStr.length; i++) {
            System.out.println(equalStr[i]);
         }
      }
   }
}

ここでは、操作をオブジェクト指向プログラミングを示す関数にカプセル化します。

public class Demo {
   static void divide_string(String input_string, int N){
      int string_length = input_string.length();
      System.out.println("The length of the string is: " +string_length);
      int temp = 0, string_parts = string_length/N;
      String[] equalStr = new String [N];
      if(string_length % N != 0) {
      System.out.println("The string cannot be divided int "+ N +" parts.");
      } else {
         for(int i = 0; i < string_length; i = i+string_parts) {
            String part = input_string.substring(i, i+string_parts);
            equalStr[temp] = part;
            temp++;
         }
         System.out.println(N + " equal parts of given string are ");
         for(int i = 0; i < equalStr.length; i++) {
            System.out.println(equalStr[i]);
         }
      }
   }
   public static void main(String[] args) {
      String input_string = "Java Program is fun!";
      System.out.println("The string is defined as: " +input_string);
      int N = 4;
      divide_string(input_string, N);
   }
}
