Java 8 - The String Class

Lets look at some code to illustrate the above scenario and prove that the str1 and str2 reference variables point to the same object, so that we can see the reuse of strings in the string constant pool: package info.java8; /* String immutability and the String Constant Pool */ import static java.lang.Math.acos; public class TestString { public static void main(String[] args) { String str1 = "java"; System.out.println("str1 = " + str1); str1 = "tutor"; System.out.println("str1 = " + str1); str1 = "javatutor"; String str2 = "javatutor"; System.out.println("str1 = " + str1); System.out.println("str2 = " + str2); System.out.println(str1 == str2); } }

August 4, 2022 - The most important point to understand is how Strings get created in java. When we create a String using string literal, it doesn’t change the value of original String. It creates a new String in the string pool and change the reference of the variable. So original string value is never changed and that’s why Strings are immutable. Below program proofs our statement, read out the comments for proper understanding the concept.
