Java运行时消息的错误

Question

I have a problem with the "output" of the program. Could you tell me if it's possible to discover the bug in the program?

/**
 * @(#)Java_test.java
 *
 * Java_test application
 *
 * @author 
 * @version 1.00 2018/8/8
 */

public class Java_test {

    public static void main(String[] args) {

        // TODO, add your application code
        int a = 5;
        a = a + 1;
        System.out.println(a);
    }
}

----Configuration: Java_test - JDK version -10.0.2 <Default> - <Default>--------------------(Build Output)
javac: invalid flag: C:\Users\estel\OneDrive\Documents\JCreator LE\MyProjects\Java_test\src\Java_test.java 
Usage: javac <options> <source files>
use --help for a list of possible options

Process completed.

Answer 1

您的代码很好，编译失败，因为文件路径中有空格，您需要将其用引号引起来，如下所示： javac "C:\\Users\\estel\\OneDrive\\Documents\\JCreator LE\\MyProjects\\Java_test\\src\\Java_test.java"
