比较结果！！！！！！！！！！！

[sam_xcx]

class x13
{
public static void main(String[] args)
{
int n3="JAVELine".compareToIgnoreCase("javelinek");
System.out.println((int)'k');
System.out.println(n3);

}
}

请不要在机器上运行该程序，请问n3的值是多少？？
若换成
int n3="JAVE".compareToIgnoreCase("javeline");

n3又是多少，有规律吗？？

public int compareToIgnoreCase(String str)
Compares two strings lexicographically, ignoring case considerations. This method returns an integer whose sign is that of this.toUpperCase().toLowerCase().compareTo( str.toUpperCase().toLowerCase()).
Note that this method does not take locale into account, and will result in an unsatisfactory ordering for certain locales. The java.text package provides collators to allow locale-sensitive ordering.

Parameters:
str - the String to be compared.
Returns:
a negative integer, zero, or a positive integer as the the specified String is greater than, equal to, or less than this String, ignoring case considerations

0完全相同,其它则不同

n3的值应该是-1，如果你变换字符的长度的话，应该以字符长度差作为返回值，另外强制类型转换，返回的是10进制的数值。
