Wie bekomme ich den Index der Unterschiede in String von Index zu Index?

Question

Ich habe zwei Strings:

String s1 = "D3516025204  StackOverflow is good."; 
String s2 = "D3516025204  StackOverflow Nice to see you."; 

Zuerst sowohl für Zeichen der Zeichenfolge vergleichen und die Indizes oder Spalte keine drucken. wenn die Charaktere verschieden sind. Ich muss die Leerzeichen in die Zeichenfolge einschließen.

Wie in oben string:

Differenz der Indizes von s1 und s2: 34 bis 48

Ich versuchte unter:

 char[] first = text1.toLowerCase().toCharArray(); 

     char[] second = text2.toLowerCase().toCharArray(); 

     int minimum = Math.min(first.length, second.length); 

     StringBuffer buffer = new StringBuffer(); 

     for (int i = 0; i < minimum; i++) { 

      if (first[i] != second[i]) { 
       do{ 
       //System.out.print(first[i]+" "+second[i]); 
       System.out.println(text1.offsetByCodePoints(first[i],text1.indexOf(second[i]))); 

      }while(first[i] == second[i]); 
     } 

     }

String text1 = "D8516025209  StackOverflow is good."; 
    String text2 = "D3516025204  StackOverflow Nice to see you."; 

    int minimum = Math.min(text1.length(), text2.length()); 
    int maximum = Math.max(text1.length(), text2.length()); 

    StringBuilder stringBuilder = new StringBuilder("Difference of indices from s1 and s2: "); 
    StringBuilder text1Diff = new StringBuilder(); 
    StringBuilder text2Diff = new StringBuilder(); 
    int index = 0; 

    while (index < minimum) 
    { 
     if (text1.charAt(index) != text2.charAt(index)) 
     { 
      stringBuilder.append(stringBuilder.length() > 0 ? ", " : "").append(index + 1).append(" - "); 
      text1Diff.append(text1Diff.length() > 0 ? ", " : ""); 
      text2Diff.append(text2Diff.length() > 0 ? ", " : ""); 

      while ((index < minimum) && (text1.charAt(index) != text2.charAt(index))) 
      { 
       text1Diff.append(text1.charAt(index)); 
       text2Diff.append(text2.charAt(index)); 
       index++; 
      } 

      if (index == minimum) 
      { 
       stringBuilder.append(maximum); 
       index = maximum; 

       if (maximum == text1.length()) 
        text1Diff.append(text1.substring(minimum)); 
       else 
        text2Diff.append(text2.substring(minimum)); 
      } 
      else 
       stringBuilder.append(index); 
     } 
     index++; 
    } 

    if (minimum != maximum && index < maximum) 
    { 
     stringBuilder.append(stringBuilder.length() > 0 ? ", " : "").append(minimum + 1).append(" - ").append(maximum); 

     if (maximum == text1.length()) 
      text1Diff.append(text1.substring(minimum)); 
     else 
      text2Diff.append(text2.substring(minimum)); 
    } 

    System.out.println(stringBuilder.toString()); 
    System.out.println("Differences: "); 
    System.out.println(text1Diff.toString()); 
    System.out.println(text2Diff.toString());

dies versuchen.

String s1 = "D3516025204  StackOverflow is good."; 
    String s2 = "D3516025204  StackOverflow Nice to see you."; 

    if(s1.length() > s2.length()){ 
     for(int i=0; i< s1.length() - s2.length(); i++) 
      s2+=" "; 
    }else{ 
     for(int i=0; i< s2.length() - s1.length(); i++) 
      s1+=" "; 
    } 
    char[] c1 = s1.toCharArray(); 
    char[] c2 = s2.toCharArray(); 

    System.out.print("Difference is: "); 
    for(int i=0; i<c1.length; i++){ 
     if(c1[i]!=c2[i]){ 
      System.out.print(i+", "); 
     } 
    }

class CrazySolution { 
public static void main(String[] args) throws Exception { 
    BufferedReader br = new BufferedReader(new InputStreamReader(System.in)); 
    String line = br.readLine(); 
    String line1 = br.readLine(); 
    //process() 
    int lenofLine = line.length(); 
    int lenofLine1 = line1.length(); 
    int finalLen = Math.min(lenofLine, lenofLine1); 

    for (int i = 0; i < finalLen; i++) { 
     if (line.charAt(i) != line1.charAt(i)) 
      { 
      System.out.println(i); 
     break; 
     } 
    } 
    System.out.println(lenofLine == lenofLine1 ? -1 : finalLen); 

}

Werfen Sie einen Blick auf apache.commons.lang3.StringUtils oder dieses post

mit StringUtils.difference (String zuerst, String 2.) Ihr Code könnte so aussehen:

public static void main(String[] args) { 
    String s1 = "D3516025204  StackOverflow is good."; 
    String s2 = "D3516025204  StackOverflow Nice to see you."; 
    String s = StringUtils.difference(s1, s2); 
    int at = StringUtils.indexOfDifference(s1, s2); 
    System.out.println(at + "-" + s2.length()); 
    System.out.println(s); 
}
