[Solved] Split with specials character and print string value [closed]

by


Here is my attempt.

public static String first_match(String[] str, String toMatch) {
    boolean match = false;
    StringBuilder output = new StringBuilder();

    for (int i=0; i<str.length; i++) {
        if (str[i].equals(toMatch)) {
            match = true;
        }
        if (match){
            output.append(str[i]);
            if (i != str.length-1) { 
                output.append("//"); 
            }
        }
    }

    return output.toString();
}

Using the above method for:

String val1 = "Start//complete//First//com//upload//First//download";
String val2 = "First";
String[] splitObject = val1.split("//");

String out = first_match(splitObject, val2);
System.out.println(out);

it gives output:

First//com//upload//First//download

EDIT:
I just realised from the comment that it could be done easier with the following:

public static String firstMatch(String str, String toMatch) {
    int index = str.indexOf(toMatch);
    if (index == -1) return "";
    return str.substring(index);
}

String out1 = firstMatch(val1, val2);

EDIT 2:
And here’s another one-liner way.

val1.replaceFirst(".*?" + val2, val2)
