Divide a string in N equal parts in Java

To check whether the string can be divided into N equal parts, we need to divide the length of the string by n and assign the result to variable characters, If the characters comes out to be a floating point value, we cannot divide the string otherwise run for loop to traverse the string and divide the string at every chars interval.

ALGORITHM

• STEP 1: start
• STEP 2: define str = “aaaabbbbcccc”
• STEP 3: define len
• STEP 4: set n =3
• STEP 5: set  temp = 0.
• STEP 6: chars = len/n
• STEP 7: define String[] equal str.
• STEP 8: IF (len %n!=0)
  then PRINT (“String can’t be divided into equal parts”)
  else go to step 9
• STEP 9: SET i =0.
• STEP 10: repeat step 11 to step 14 until  i<len
• STEP 11: define substring part.
• STEP 12: equalstr [temp] = part
• STEP 13: temp = temp + 1
• STEP 14: i = i + chars
• STEP 15: print n
• STEP 16: SET i=0. repeat step 18 and 19 until  i<equalstr.length
• STEP 17: print equalstr[i]
• STEP 18: i = i + 1
• STEP 19: End

  public class DivideString {  
      public static void main(String[] args) {  
            String str = "aaaabbbbcccc"; 
          int len = str.length();  
          int n = 3;  
          int temp = 0, chars = len/n;    
          String[] equalStr = new String [n];    
          if(len % n != 0) {  
              System.out.println("Sorry this string cannot be divided into "+ n +" equal parts.");  
          }  
          else {  
              for(int i = 0; i < len; i = i+chars) {   
                  String part = str.substring(i, i+chars);  
                  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]);  
                  }  
              }  
          }  
  }

  OUTPUT

  3 equal parts of given string are
  aaaa
  bbbb
  cccc
