import java.lang.Integer; public class StudyTonight { public static void main(String[] args) { String s1 = "23"; String s2 = "132"; int n1 = Integer.parseUnsignedInt(s1); //converts the passed string as unsigned integer int n2 = Integer.parseUnsignedInt(s2); //converts the passed ...
publicstaticintparseHexToDecimal(StringhexString){// 使用parseInt函数将16进制字符串转换为十进制数returnInteger.parseInt(hexString,16);} 1. 2. 3. 4. 解释: parseInt是一个静态方法,可以将一个字符串解析为整数。 hexString是要转换的16进制字符串。
In Java, you can convert a string to a character using the charAt() method of the String class. This method takes an index as an argument and returns the character at that index.
Integer.valueOf(String s)的源码: publicstaticIntegervalueOf(String s)throwsNumberFormatException {returnInteger.valueOf(parseInt(s,10)); } 从源码可以看到: Integer.parseInt(String s)将会返回int常量。 Integer.valueOf(String s)将会返回Integer类型的对象。
