Get System Java Compiler and check sourceVersion

Example to get System Java Compiler by calling ToolProvider.getSystemJavaCompiler(), and check sourceVersion with getSourceVersions().

package java_javacompiler;

import java.util.Set;
import javax.lang.model.SourceVersion;
import javax.tools.JavaCompiler;
import javax.tools.ToolProvider;

public class Java_JavaCompiler {

    public static void main(String[] args) {
        JavaCompiler javaCompiler = ToolProvider.getSystemJavaCompiler();
        System.out.print(javaCompiler.toString());
        
        Set<SourceVersion> sourceVersion;
        sourceVersion = javaCompiler.getSourceVersions();
        
        for (SourceVersion version : sourceVersion) {
            System.out.print(version.name() + "\n");
        }
        
    }
    
}
