The method compile(ClassGenerator, MethodGenerator) in the type Expression is not applicable for the

本文解决了一种常见的正则表达式使用错误,即在Java中使用Pattern.compile()方法时,由于包导入错误导致的编译问题。文章强调了正确的包导入对于避免此类错误的重要性。

废话不多说直接上代码

正常使用正则表达式的时候需要把string类型先通过compile进行编译,如下

String regEx="[^0-9]";   
Pattern pattern = Pattern.compiler(regEx);

但是有部分人会遇到如下的问题!
在这里插入图片描述

错误提示翻译过来大概是:类型表达式中的方法编译(ClassGenerator, MethodGenerator)不适用于参数(字符串)

那么这个时候去看一下你的包导入的正不正确在这里插入图片描述

如果你导入的不是util中的包 那么你放心他是一定会报错的

Cross-compiling Parsec benchmark for ARM architecture involves setting up a build environment on your host machine (likely x86 or x64) that can generate code for ARM targets. Here's a general outline of the steps: 1. **Install required tools**: Ensure you have installed a compiler and toolchain that supports ARM, like `gcc-arm-none-eabi` or `clang-arm`. 2. **Set up target environment**: You'll need to configure the toolchain with the correct paths and settings for the ARM target. This may involve creating a separate configuration file or specifying flags when invoking the compiler. ```sh export CC=arm-none-eabi-gcc export CXX=arm-none-eabi-g++ ``` 3. **Download Parsec**: Download the latest version of Parsec, which is a benchmarking suite, and extract it to a suitable location. 4. **Configure Makefile**: If Parsec has a Makefile, modify it to specify the target architecture. Look for lines similar to `CC`, `CFLAGS`, or `LDFLAGS`. Add or update them as needed, using the ARM-specific versions. 5. **Build for ARM**: Run `make clean && make` in the Parsec directory, replacing `make` with the appropriate command for your build system (e.g., `ninja` if you're using Ninja). ```sh make TARGET=arm-linux-gnueabihf ``` 6. **Test on ARM device or emulator**: Copy the generated `.elf` (executable) file to an ARM device or use an emulator to run it. **Related questions:** 1. What specific version of the ARM toolchain do I need? 2. How can I deal with dependencies if they don't have ARM builds available? 3. Are there any libraries or patches I need to include for compatibility with Parsec on ARM?
