Which of the following statements is preferred to create a string "Welcome to Java"?
a. String s = "Welcome to Java";
b. String s = new String("Welcome to Java");
c. String s; s = "Welcome to Java";
d. String s; s = new String("Welcome to Java");
a. String s = "Welcome to Java";
(a) is better than (b) because the string created in (a) is interned. Since strings are immutable and are ubiquitous in programming, to improve efficiency and save memory, the JVM uses a unique instance for string literals with the same character sequence. Such an instance is called interned. The JVM (a) is simpler than (c).
