You can convert an array to a set in Java using different methods, such as “Arrays.asList()”, “Collections.addAll()”, “Set.of()” and Java 8 Stream API.

You can use built-in parse methods, Apache Commons Lang, and regular expressions, to check if a string is numeric in Java.

In Java, the lastIndexOf() of the String class retrieves the last occurrence (position) of the provided character or substring.

To split a string by whitespaces in Java, use the split() method on the provided string and specify the whitespace as a delimiter.

The modulo operator in Java performs division on given values and retrieves the remainder as output. It is denoted with a percent sign “%”.
