'String.format' call can be replaced with string templates

Last modified: 03 December 2024

Reports String.format calls that can be replaced with string templates.

Using string templates makes your code simpler.

The quick-fix replaces the call with a string template.

Example:

fun main() {
    val id = "abc"
    val date = "123"
    val s = String.format("%s_%s_%s", id, date, id)
}

After the quick-fix is applied:

fun main() {
    val id = "abc"
    val date = "123"
    val s = "${id}_${date}_$id"
}
