oh I learn something from this example I really like it 🙂 especially the import java.util.Arrays; so helpful :).
GreatWork javaex 🙂
String[] strArray =
new String[]{“Java”, “String”, “Array”, “To”, “String”, “Example”};
Use the below code to replace
String s=Arrays.toString(strArray).replaceAll(“(\\[|\\]|,| )”, “”);
