Frequently Asked Questions

Is String Thread-Safe? How?

Because strings are immutable, they are thread-safe. Because immutability assures that its instances will not be modified across different threads, any class that is immutable inherently qualifies for thread safety.

For example, if a thread modifies the value of a string, a new String is generated rather than altering the current one.

What Is the String Constant Pool?

The String constant pool, sometimes known as the String intern pool, is a specific memory location where the JVM saves String instances.

What is the difference between Length and capacity in Java StringBuffer?

The capacity of a StringBuffer object is the total amount of characters it can contain. On the other hand, Length is the number of characters already contained in the StringBuffer object.
