We have seen sometimes the strings are made using char s[], or sometimes char *s. So here we will see is there any difference or they are same?There are some differences. The s[] is an array, but *s is a pointer. For an example, if two declarations are like char s[20], and char *s respectively, then by using sizeof() we will get 20, and 4. The first one will be 20 as it is showing that there are 20 bytes of data. But second one is showing only 4 as this is the size of one pointer variable. For the ... Read More
Let’s say the following is String array, which we have converted to List −Arrays.asList("DE", "GH", "JK", "MN", "PQ", "RS", "TU", "VW", "XY", "BC")Now filter String stream and map to lower case −.stream() .filter(a-> a.startsWith("V")) .map(String::toLowerCase)To sort now, use the sorted() and display using forEach().The following is an example to filter string stream and map to lowercase −Exampleimport java.util.Arrays; public class Demo { public static void main(String[] args) throws Exception { Arrays.asList("DE", "GH", "JK", "MN", "PQ", "RS", "TU", "VW", "XY", "BC") .stream() .filter(a-> a.startsWith("V")) .map(String::toLowerCase) ...
