我已多次尝试清除控制台并编写此 Runtime.getruntime.exec(“cls”); 但未获得任何结果,表示控制台未被清除窗

\b
可能会成功。每个字符打印一个System.out.print("Foo");
System.out.print("\b\b\b");
System.out.print("Bar");
。
String foo = "Foo";
System.out.print(foo);
for (int i = 0; i < foo.length(); i++) {
System.out.print("\b");
}
System.out.print("Bar");
打印“Bar”
var server = http.createServer(function(request, response){
console.log('Connection');
var path = url.parse(request.url).pathname;
switch(path){
case '/':
response.writeHead(200, {'Content-Type': 'text/html'});
response.write('hello world', function(err) { response.end(); });
break;
case '/index.html':
fs.readFile(__dirname + path, function(error, data){
if (error){
response.writeHead(404);
response.write("opps this doesn't exist - 404");
}
else{
response.writeHead(200, {"Content-Type": "text/html"});
response.write(data, function(err) { response.end(); });
}
});
break;
default:
response.writeHead(404);
response.write("opps this doesn't exist - 404", function(err) { response.end(); });
break;
}
});
使用循环的结果相同。
