Concatenation of String array to String

This program will help to concatenate String array to a simple string with a delimiter( if require).

public class StrArrtoStr {

public static void main(String[] args) {

String weeks_days[] = new String[7];

weeks_days[0] = "Sunday";

weeks_days[1] = "Monday";

weeks_days[2] = "Tuesday";

weeks_days[3] = "Wednesday";

weeks_days[4] = "Thursday";

weeks_days[5] = "Friday";

weeks_days[6] = "Saturday";

StringBuffer finalString = new StringBuffer();

if (weeks_days.length > 0) {

finalString.append(weeks_days[0]);

for (int i = 1; i < weeks_days.length; i++) {

finalString.append(",");

finalString.append(weeks_days[i]);

}

}

System.out.println("Concatenation of String array to String:::"

+ finalString.toString());

}

}

In the above example, we have String array of length 7 having items(weeks). We need to concatenate all these into a one string.

The above program will provide a final output which is as follows:

Concatenation of String array to String::: Sunday,Monday,Tuesday,Wednesday,Thursday,Friday,Saturday
