System.out.println(String.format("%1$,09d", -3123)); 我的Eclipse老是报The method format(String, Object[]) in the type String is not applicable for
the arguments (String, int)这个呢！？不知道市哪里用错了，请教各位高

format(String, Object[])
接受的参数是一个字符串对象和一个Object对象，而INT是基本类型，不是对象
是要搞清楚。不过可以定义一个INTEGE对象
public static void main (String args[]){
String string = "1000";
String str = String.format("%1$s:%2$s", string, string+"1000");
System.out.print(str);
}
}
1000:10001000
* Returns a formatted string using the specified format string and
* arguments.
*
* <p> The locale always used is the one returned by {@link
* java.util.Locale#getDefault() Locale.getDefault()}.
*
* @param format
* A <a href="../util/Formatter.html#syntax">format string</a>
*
* @param args
* Arguments referenced by the format specifiers in the format
* string. If there are more arguments than format specifiers, the
* extra arguments are ignored. The number of arguments is
* variable and may be zero. The maximum number of arguments is
* limited by the maximum dimension of a Java array as defined by
* the <a href="http://java.sun.com/docs/books/vmspec/">Java
* Virtual Machine Specification</a>. The behaviour on a
* <tt>null</tt> argument depends on the <a

*
* @throws IllegalFormatException
* If a format string contains an illegal syntax, a format
* specifier that is incompatible with the given arguments,
* insufficient arguments given the format string, or other
* illegal conditions. For specification of all possible
* formatting errors, see the <a
