How can i delete all letters from String? I've got given String:

val stringData ="ABC123.456"

Output value:

val stringData ="123.456"

CodePudding user response：

We can try regex replacement here:

val regex = """[A-Za-z] """.toRegex()
val stringData = "ABC123.456"
val output = regex.replace(stringData, "")
println(output)  // 123.456
