Here’s some Go

package main

import (
    "fmt"
)

func main() {
    fmt.Println("Hello world!")
    fmt.Println("Hello world!")
    fmt.Println("Hello world!")
    fmt.Println("Hello world!")
    fmt.Println("Hello world!")
    fmt.Println("Hello world!")
    fmt.Println("Hello world!")
    fmt.Println("Hello world!")
    fmt.Println("Hello world!")
    fmt.Println("Hello world!")
    fmt.Println("Hello world!")
}

Here’s some Java

public static void main() {
    System.out.println("Hello world!");
    System.out.println("Hello world!");
    System.out.println("Hello world!");
    System.out.println("Hello world!");
    System.out.println("Hello world!");
    System.out.println("Hello world!");
    System.out.println("Hello world!");
    System.out.println("Hello world!");
    System.out.println("Hello world!");
    System.out.println("Hello world!");
    System.out.println("Hello world!");
}

Here’s some C

int main() {
    printf("Hello world!");
    return 0;
}
