java does not have "template literals" in the same way that javascript does. however, java does support string interpolation and formatting, which can achieve similar results. in java, you typically use `string.format()`, `stringbuilder`, or string concatenation.

string formatting in java

java provides a powerful way to format strings using the `string.format()` method. this method allows you to create formatted strings by embedding variables directly into a string template.

#### basic syntax of `string.format()`

the basic syntax of `string.format()` is as follows:

`%s` is a placeholder for a string.
`%d` is a placeholder for an integer.
`%f` is a placeholder for a floating-point number.

example: using `string.format()`

here’s a simple example demonstrating how to use `string.format()` for string interpolation in java:

#### output:

using `stringbuilder` for dynamic strings

for more complex scenarios, especially when constructing strings dynamically in loops or with multiple appends, consider using `stringbuilder`. here's an example:

#### output:

conclusion

while java does not have template literals like javascript, it provides powerful string formatting options through `string.format()` and `stringbuilder`. these tools allow you to create dynamic and formatted strings that can include variables easily and clearly.

for more advanced string manipulation, you might also consider using libraries like apache commons lang (`stringutils`) or java's `textblock` feature (introduced in java 13) for multi-line strings.
