There are different methods such as equals, compareTo, etc., available in order to compare the strings. equals() method compares two strings based on the string content. If orders is a stream of purchase orders, and each purchase order contains a collection of line items, then the following produces a stream containing all the line items We can concatenate the strings using this method and at the same time, we can format the output concatenated string. Alternatively, we can use String.format() method, string concatenation operator etc.. We can convert int to String in java using String.valueOf() and Integer.toString() methods. The index of the first character is 0, the second character is 1, and so on. and StringBuffer will be updated to use the same representation, as The result will have the value 0 if the argument string is equal to this string; a value less than 0 if this string is lexicographically less than the string argument; and a value greater than 0 if this string is lexicographically greater than the string argument. Examples might be simplified to improve reading and learning. Since the equalsIgnoreCase methodis used, str1 and str2 are equal even though they are of different cases(small case and upper case).
