You can use following method.

public static String replaceFirstOccurrenceOfString(String inputString, String stringToReplace,
        String stringToReplaceWith) {

    int length = stringToReplace.length();
    int inputLength = inputString.length();

    int startingIndexofTheStringToReplace = inputString.indexOf(stringToReplace);

    String finalString = inputString.substring(0, startingIndexofTheStringToReplace) + stringToReplaceWith
            + inputString.substring(startingIndexofTheStringToReplace + length, inputLength);

    return finalString;

}
