步骤1:将字符转换为数字 在Java中,可以使用Character.getNumericValue(char ch)方法将字符转换为数字。以下是代码示例: // 将字符转换为数字charc='5';// 定义一个字符 '5'intnum=Character.getNumericValue(c);// 使用Character.getNumericValue()方法将字符转换为数
public int compareTo(String anotherString) { int len1 = value.length; int len2 = anotherString.value.length; //取数组长度里面最小的 int lim = Math.min(len1, len2); // 获得两个数组,这两个数组就是string的属性 char v1[] = value; char v2[] = anotherString.value; int k = 0; w...

(1)不忽略字符串大小写情况下字符串的大小比较方法compareTo(another str) 格式:int result = str1.compareTo(str2); 输出三种比较结果:若该字符串的Unicode值<参数字符串的Unicode值,结果返回一负整数;若若该字符串的Unicode值=参数字符串的Unicode值,结果返回0;若该字符串的Unicode值>参数字符串的Unicode值,结...
publicvoidcompareVariable(){int age;Object object;System.out.println(age);// 编译错误System.out.println(object);// 编译错误} 在Golang中:对于基本类型来讲,声明即初始化;对于引用类型,声明则初始化为nil。 代码语言:javascript 代码运行次数:0

static int compare(CharSequencecs1,CharSequencecs2) Compares twoCharSequenceinstances lexicographically. Returns a negative value, zero, or a positive value if the first sequence is lexicographically less than, equal to, or greater than the second, respectively. ...
int compareTo(T o)//返回是一个整型 将此对象与指定的对象进行比较 以进行排序 返回一个负整数,零或者正整数,因为该对象小于,等于或大于指定对象; person1.compareTo(person2); 如果返回值是负数,就证明 person1 小于 person2 排序 person1 排在 person2 前面 如果返回值是0,就证明相等,不存了 如果是个...
