We will see two programs to reverse a string. First program reverses the given string using recursion and the second program reads the string entered by user and then reverses it. To understand these programs you should have the knowledge of following co
The String class represents character strings. All string literals in Java programs, such as "abc", are implemented as instances of this class. Strings are constant; their values cannot be changed after they are created. String buffers support mutable strings. Because String objects are immutable ...

The 15 JEPs delivered with Java 21 are grouped into six categories mapping to key long-term Java technology projects and hardware support. Project Amber JEP 430: String Templates (Preview) JEP Goals: Simplifies the writing of Java programs by making it easy to express strings that include valu...
One such accessor method related to strings is the length () method. This returns the number of characters in the string object. public class Exercise { public static void main(String args[]){ String s1="Hello"; String s2="World"; System.out.println("string length is: "+s1.length())...
Here is an example that starts a process with a modified working directory and environment, and redirects standard output and error to be appended to a log file: text/java {@code ProcessBuilder pb = new ProcessBuilder("myCommand", "myArg1", "myArg2"); Map<String, String> env = pb.envi...
