What Is the Java Equivalent of .NET's String.Format?

Is there a Java equivalent to .NET's String.Format method?

In .NET, the `String.Format` method is widely used for string formatting by substituting placeholders with values. Java offers similar functionality through various methods available in the `String` class, specifically using `String.format()`. This method provides a flexible way to format strings using format specifiers, making it a powerful alternative to .NET's `String.Format`.

String name = "John";
int age = 30;
String formattedString = String.format("My name is %s and I am %d years old.", name, age);
System.out.println(formattedString); // Output: My name is John and I am 30 years old.

Solutions

• Use `String.format()` for formatting strings in Java.
• Utilize `MessageFormat` for more complex scenarios involving argument formatting.
• For a more modern approach, consider using `StringBuilder` or string concatenation for simple formatting needs.

Mistake: Using incorrect format specifiers (e.g., using %d for strings)

Solution: Ensure that format specifiers match the data type of corresponding variables.

Mistake: Forgetting to escape special characters in the format string (e.g., using % without an appropriate specifier)

Solution: Use double percentage signs (%%) to escape the '%' character.
