遇到个php转java的问题

大佬们在哪 帮一下啊

. 连接字符串

我知道了 居然是string的+法

import java.text.*;
import java.util.Date;
public class FilePathMaker {
public String AppendDate( String bbb, String ccc, String ddd ) {
String aaa;
aaa = bbb + ccc + ddd;
DateFormat fmt = new SimpleDateFormat( "yyyyMMdd" );
aaa += fmt.format( new Date() );
return aaa;
}
public static void main( String[] args ) {
String s1 = new String( "Current" );
String s2 = new String( " " );
String s3 = new String( "date: " );
FilePathMaker maker = new FilePathMaker();
System.out.println( maker.AppendDate( s1, s2, s3 ) );
}
}
差不多就是这么个意思
