我收到此错误:
SyntaxError: hello.rb:13: syntax error, unexpected tIDENTIFIER
public HelloWorld( InputStream data ) throws IOException {
HelloWorld.rb 是:
require "java"
import java.io.FileInputStream;
import java.io.InputStream;
import java.io.IOException;
import opennlp.tools.postag.POSModel;
import opennlp.tools.postag.POSTaggerME;
public class HelloWorld {
private POSModel model;
public HelloWorld( InputStream data ) throws IOException {
setModel( new POSModel( data ) );
}
public void run( String sentence ) {
POSTaggerME tagger = new POSTaggerME( getModel() );
String[] words = sentence.split( "\\s+" );
String[] tags = tagger.tag( words );
double[] probs = tagger.probs();
for( int i = 0; i < tags.length; i++ ) {
System.out.println( words[i] + " => " + tags[i] + " @ " + probs[i] );
}
}
private void setModel( POSModel model ) {
this.model = model;
}
private POSModel getModel() {
return this.model;
}
public static void main( String args[] ) throws IOException {
if( args.length < 2 ) {
System.out.println( "HelloWord <file> \"sentence to tag\"" );
return;
}
InputStream is = new FileInputStream( args[0] );
HelloWorld hw = new HelloWorld( is );
is.close();
hw.run( args[1] );
}
}
跑步时ruby HelloWorld.rb "I am trying to make it work"
当我运行它时,HelloWorld.java "I am trying to make it work"
它工作得很好,当然.java
不包含该require java
语句。
编辑:
我按照以下步骤操作。
的输出jruby -v
