在Maven上使用println没有输出到控制台

Question

So whenever I build and test my maven package i am not getting an output and the program auto closes, I have tried this on Eclipse and Netbeans and still no heed, thanks in advance and the code is below:

public static void main(String[] args) {
    // TODO Auto-generated method stub

    Boolean end = false;
    while(end = false){
    System.out.println("Enter your command(for list of commands press h): ");
    Scanner scanner = new Scanner(System.in);
    String command = scanner.nextLine();
    if(command == "h"){
        System.out.println("start   starts basic program");
        System.out.println("start1  starts twitter based program(in development)");
        System.out.println("api     sets api");
        System.out.println("time     sets check time");

    }else if( command == "start"){
        mainmethod();
    }else if(command == "time"){

    }else if( command == "end"){
                end = true;
            }
    }


}

Answer 1

your code means:

while(false){.....} 

Please change from:

while(end = false){
......
}

into:

while(end == false){
......
}

Answer 2

它是“ ==”而不是“ =”。end == false
