Java一个简单问题
大家帮忙看看那里出问题了？

public class SecondJavaForC
{
public static void main(String[] agrs)
{
System.out.printf("s%！ Java程序hi","c语言Fan").println();
}
}

运行结果：
Exception in thread "main" java.util.UnknownFormatConversionException: Conversion = '！'
at java.util.Formatter.checkText(Formatter.java:2500)
at java.util.Formatter.parse(Formatter.java:2482)
at java.util.Formatter.format(Formatter.java:2411)
at java.io.PrintStream.format(PrintStream.java:899)
at java.io.PrintStream.printf(PrintStream.java:800)
at SecondJavaForC.main(SecondJavaForC.java:6)

[解决办法]
字符格式有问题
s%
改改就好
