You can do it with the help of substring() and replaceAll() methods

String value="MOTOR PRIVATE CAR-PACKAGE POLICY";
value = value.substring(0, value.indexOf("-")); //get the string till -
value = value.replaceAll("\\s", "-"); //replace all the space chars with -
System.out.println(value);

I have used String.replaceAll() instead of String.replace() to use the regex for white space

\s stands for white space character and and while adding it as regex, we need to escape it with an extra \ so --> \\s

indexOf("-") method returns the index of first occurrence of the String passed, which should be the 2nd parameter to substring method, which is the endIndex

You can split the string with '-' which gives you the part of the string in which you need to insert ' '. Split the string again with ' ' and insert '-' b/w the words.

String value="MOTOR PRIVATE CAR-PACKAGE POLICY";
String[] phrase = value.split("-");
String[] words = phrase[0].split(" ");

String newValue;
for(int i = 0; i < words.length; i++)
  newValue += words[i] + "-";

public class StringModify {

/**
* @param args
*/
public static void main(String[] args) {

   try {
   String value="MOTOR PRIVATE CAR-PACKAGE POLICY";
   System.out.println("Value-------------------->"+value.replaceFirst("\\s*\\w+\\s+\\w+$", ""));

   value = value.substring(0,value.indexOf("-")); // get the words before "-"
   value = value.replace(" ", "-"); // replace space with hiphen
   System.out.println(value);
} catch (Exception e) {

   e.printStackTrace();
}


}

You can do it in two steps:

  1. To get all the words from the string before "-", you can use String substring and indexOf methods.
  2. To replace empty spaces with hiphen(-), you can use the String replace method.

Here is the code:

String value="MOTOR PRIVATE CAR-PACKAGE POLICY";
value = value.substring(0,value.indexOf("-")); // get the words before "-"
value = value.replace(" ", "-"); // replace space with hiphen
System.out.println(value);
