我愿检查一下:ch,其定义为(char ch = ,在0x20(空间)至0x7E(~)之间。

我尝试了许多方法,但给我错了答案。

例如:

if (ch > 0x20 or ch <0x7F) then

if (ch >     or ch <  ~ ) then

我如何能够这样做?

成就

问题回答
if( ch >= 0x20 && ch <= 0x7e) {
 // ch is in your range
}

if( ch >=      && ch <=  ~ ) {
// ch is in your range
}

该法典具有所有非属性。 在这种情况下,他们被带走,但你可以改换,做你想要做的事情。

String resultString = subjectString.replaceAll("[^\x00-\x7F]", "");
