`for(:)` is not a valid syntax in any programming language.
The `for` loop is a control flow statement used in many programming languages, including Java, C++, and Python. It allows you to iterate over a sequence of values or elements and execute a block of code for each iteration. The general syntax for a `for` loop is:
```
for (initialization; condition; increment/decrement) {
// code to be executed
}
```
The `initialization` statement is executed only once before the loop starts. The `condition` is evaluated before each iteration, and if it is true, the loop continues. The `increment/decrement` statement is executed after each iteration.
The `for(:)` syntax you provided is not valid in any programming language.
