    • Immutable strings prevent accidental modification of data.

    • Immutable strings allow for safe sharing of data between different parts of a program.

    • Immutable strings help in thread safety by avoiding concurrent modification issues.

    • Example: String str = "hello"; str.concat(" world"); // This does not modify the original string, but creates a new one

    • String concatenation creates a new string object each time, while StringBuilder allows for efficient string manipulation.

    • StringBuilder is more efficient for concatenating multiple strings in a loop.

    • Example: String str = "Hello"; StringBuilder sb...
