Strings, StringBuffer<\/strong><\/h4>\n\n\n\n

In Java, strings are a sequence of characters, represented by the String class. The String class is immutable, meaning once a string object is created, it cannot be modified. On the other hand, StringBuffer is a mutable class that allows modification of its contents.<\/p>\n\n\n\n

Here are some differences between String and StringBuffer:<\/p>\n\n\n\n

Immutability: As mentioned earlier, String is immutable, which means the contents of a String object cannot be changed once it is created. On the other hand, StringBuffer is mutable, and its contents can be modified.<\/p>\n\n\n\n

Performance: Because String is immutable, every time you modify its contents, a new String object is created. This can be a performance issue when you need to modify a string multiple times. In contrast, StringBuffer is designed for efficient string manipulation, and modifying its contents doesn’t create a new object every time.<\/p>\n\n\n\n

Thread-safety: String is thread-safe because it is immutable. On the other hand, StringBuffer is not thread-safe, but there is a thread-safe version of StringBuffer called StringBuilder.<\/p>\n\n\n\n

Here are some examples of using String and StringBuffer in Java:<\/p>\n\n\n\n

\/\/ Creating a String object<\/p>\n\n\n\n

String str = “Hello, world!”;<\/p>\n\n\n\n

\/\/ Modifying a String creates a new String object<\/p>\n\n\n\n

str = str + ” How are you?”;<\/p>\n\n\n\n

\/\/ Creating a StringBuffer object<\/p>\n\n\n\n

StringBuffer sb = new StringBuffer(“Hello, world!”);<\/p>\n\n\n\n

\/\/ Modifying a StringBuffer doesn’t create a new object<\/p>\n\n\n\n

sb.append(” How are you?”);<\/p>\n\n\n\n

In the example above, modifying the str object creates a new String object, whereas modifying the sb object using the append method does not create a new object.<\/p>\n\n\n\n
