handling Try catch finally in Go

In Go, the try/catch/finally is implemented using the defer, panic, and recover keywords. The defer keyword is used to defer the execution of a function call until the surrounding function completes its execution. The panic keyword is used to cause a run-time panic, and the recover keyword is used to recover from a panic and resume normal execution.

Here is an example of how to use try/catch/finally in Go:

func divideByZero() {
    defer func() {
        if err := recover(); err != nil {
            fmt.Println("Error: ", err)
        }
    }()
    a := 10
    b := 0
    if b == 0 {
        panic("division by zero")
    } else {
        c := a / b
        fmt.Println("Result: ", c)
    }
}

In the above example, the divideByZero function divides a number by zero, which results in a run-time panic. We use the defer keyword to call a function that will recover from the panic, and then we use the panic keyword to cause the panic. The if err := recover(); err != nil statement checks if a panic occurred and if so, it prints out the error message.

Overall, try/catch/finally in Go can be used to handle exceptional cases in code that require special attention in order for the code to continue running as intended without crashing.
