In the following example we are assigning char values to integer variables without any typecasting. Compiler automatically doing the conversion here, this only applies when we are assigning a smaller data type to larger data type else we have to do explicit type casting. publicclassJavaExample{pub...
在Java中,char类型是16位无符号Unicode字符。要将char转换为16进制表示形式,我们可以通过将char强制转换为int类型,再使用Integer.toHexString()方法将其转换为16进制字符串。 下面是实现char转16进制的简单方法: publicclassCharToHex{publicstaticStringcharToHex(charc){returnInteger.toHexString((int)c);}publicstaticvo...
int num = 200; if (num >= 0 && num <= 255) { char ch = (char)num; printf("Safe conversion: %d -> %c\n", num, ch); } else { printf("Value out of range for char!\n"); } 问题2:负数转换 原因:负整数转换为char时,可能会得到意外的结果,因为char类型可能是有符号的。
