In Java, the String.format() method allows you to create formatted strings by embedding values into placeholders. It takes a format string and arguments, returning a new formatted string. The format string contains placeholders, represented by % symbols, which are replaced by the provided values in a specified format.
For example:
This will output: Hello, John! Your balance is $1234.56.
Common format specifiers include %s for strings, %d for integers, and %.2f for floating-point numbers.
