我正在尝试javaFx在窗口内编写多个图像的应用程序.
简短的故事是我有一个enum名为的类Candy,每个糖果都有一些属性和表示它的图像文件的路径.
在我的javafx.application类(Table)的构造函数中,我想用这些图像填充数组列表,所以到目前为止我写了这个:
public class Table extends Application {
ArrayList<Image> images;
@Override
public void start(Stage primaryStage) throws Exception {
primaryStage.setTitle("CandyFx");
primaryStage.show();
}
public Table() {
images = new ArrayList<Image>();
for (Candy candy : Candy.values()) {
File file = new File (candy.getImagePath());
Image image = new Image(file.toURI().toString());
images.add(image);
}
}
}
现在每次我想创建一个Table类的实例时,应用程序抛出一个java.lang.RuntimeException: Internal graphics not initialized yet.
我怎么能初始图形看起来我没有？
我开始使用C.我有定义全局变量的问题.例如,platformID在install.c中使用.我在main.c中声明但仍然出错:
install.c | 64 |错误:'platformID'未声明(首次在此函数中使用)|
main.c中:
#ifdef __APPLE__
#include <OpenCL/opencl.h>
#else
#include <CL/cl.h>
#endif
cl_int err;//the openCL error code/s
cl_platform_id platformID;//will hold the ID of the openCL available platform
cl_uint platformsN;//will hold the number of openCL available platforms on the machine
cl_device_id deviceID;//will hold the ID of the openCL device
cl_uint devicesN; //will hold the number of OpenCL devices in the system
#include "include/types.h"
#include "include/gaussian.h"
#include "include/args.h"
#include "include/files.h"
#include "refu/Time/rfc_timer.h"
#include <stdio.h>
...
install.c
#include "include/types.h"
#include "include/gaussian.h" …我有以下课程
class CodeRequest(@JsonProperty("phone") val phoneNumber: String)
当我使用此类的对象作为主体发送请求（使用改造）时（当未启用缩小时）一切正常，请求将以这种形式发送 {"phone": "123"}
但是使用以下内容启用缩小proguard-rules.pro将导致{"phoneNumber": "123"}请求正文。

data segment
string1 db "Lotfi", 0
string2 db "Ali ", 0
data ends
code segment
ASSUME CS: code, DS: data
start:
cld
mov ax , data
mov DS , ax
mov SI , offset string1
mov DI , offset string2
add DI , 3 ; Adding the length of destination string to the DI
mov cx , 5
rep movsb ; This should concat two strings
; Printing the result character by character …
