1肴沫、將c語言代碼寫入.c文件

try {
            BufferedWriter out = new BufferedWriter(new FileWriter("demo.c"));
            out.write("#include<stdio.h>\n" +
                    "int main(){\n" +
                    "\tprintf(\"hello linux\\n\");\n" +
                    "\treturn 0;\n" +
                    "}");
            out.close();
            System.out.println("demo.c創(chuàng)建成功！");
        } catch (IOException e) {
        }

2蕴忆、調(diào)用shell文件運行

 Process process;
        try {
            process = Runtime.getRuntime().exec("bash ./chkRun.shell");//運行我的shell腳本
            BufferedReader reader = new BufferedReader(new InputStreamReader(process.getInputStream()));
            String line;
            int exitValue = process.waitFor();
            while((line = reader.readLine())!= null){
                System.out.println(line);
            }
            if (exitValue == 0){
                System.out.println( "successfully executed the linux command");
            }
        } catch (IOException | InterruptedException e) {
            e.printStackTrace();
        }

3颤芬、java代碼整合

TestShell.java

import java.io.*;

public class TestShell {
    public static void main(String[] args) {
        try {
            BufferedWriter out = new BufferedWriter(new FileWriter("demo.c"));
            out.write("#include<stdio.h>\n" +
                    "int main(){\n" +
                    "\tprintf(\"hello linux\\n\");\n" +
                    "\treturn 0;\n" +
                    "}");
            out.close();
            System.out.println("demo.c創(chuàng)建成功！");
        } catch (IOException e) {
        }
        Process process;
        try {
            process = Runtime.getRuntime().exec("bash ./chkRun.shell");//運行我的shell腳本
            BufferedReader reader = new BufferedReader(new InputStreamReader(process.getInputStream()));
            String line;
            int exitValue = process.waitFor();
            while((line = reader.readLine())!= null){
                System.out.println(line);
            }
            if (exitValue == 0){
                System.out.println( "successfully executed the linux command");
            }
        } catch (IOException | InterruptedException e) {
            e.printStackTrace();
        }
    }
}

4套鹅、linux系統(tǒng)中上傳java文件站蝠，并且編寫shell腳本

touch chkRun.shell
vim chkRun.shell

`
`
`
`
gcc demo.c -o demo.out
./demo.out
rm demo.out
rm demo.c

5、自動化編譯java使其編譯c

javac TestShell.java
java TestShell

這就是線上編程項目的核心功能demo展現(xiàn)
