You need to use look ahead and look behind like following

    String string1="Ram-sita-laxman";
    System.out.println(Arrays.toString(string1.split("((?<=-)|(?=-))")));

In this the output will be [Ram, -, sita, -, laxman]

Notice that while the delimiter is there but not everything is in quotes cause it can't be unless you add them yourself in the array

Hope this helps.

@yami You already have the elements in an array in the answer I had givem. You can just loop the array and add the double quotes to each element

Sir, i asked kind of a different question now. not about quotes " " But how to split string in 1 operation by 4 strings: "and" "or" "(" ")" Let's say starting string was: (a=1 and b=2) or(a=3 and b=4)
