看到可以对字符串先split再join,就可以想到,我们可以想到对于这两个方法的参数可以传入不同的字符串,这样就起到了代替String的replace方法进行子串替换的功能了,而且还是全局替换。 比如希望把所有的下划线(_)替换成横杠(-): var str = 'hello_from_ider_to_world'.split('_').join('-'); document.write(st...
The split() method splits a string into an array of substrings using a regular expression as the separator.If a limit is specified, the returned array will not be longer than the limit. The last element of the array will contain the remainder of the string, which may still have ...

In this article, we've seenhow to find the char is present in the stringusing string api methods such asindexOf, lastIndexOfmethods. Finally, if index is negetive then it will return value '-1'. indexOf method is used internally incontains(),replace(), split(),isBlank(),indent()metho...

split():分割字符串,返回一个分割后的字符串数组。 getBytes():返回字符串的 byte 类型数组。 length():返回字符串长度。 toLowerCase():将字符串转成小写字母。 toUpperCase():将字符串转成大写字符。 substring():截取字符串。 equals():字符串比较。 new String("dabin")会创建几个对象? 使用这种方式会创...
代码语言:java 复制 @FunctionalInterface interface StringProcessor { String process(String str); } 然后,我们可以使用Lambda表达式来创建该接口的实例,并将字符串值返回给参数。例如,将字符串转换为大写: 代码语言:java 复制 StringProcessor toUpperCase = str -> str.toUpperCase(); String result = toUpperCase...
