急，在线 java 中怎样把 ' 换为 \'
原始字符串：
FUN FILMS FOR SUMMER-(3-1-A)-You'll smile
通过 String replace方法，把 ' 换为 \'

处理过就该是这样的:
FUN FILMS FOR SUMMER-(3-1-A)-You\'ll smile

[解决办法]
str.replace(“’”,"\\\'")试试看
[解决办法]

Java code

public class Test {    public static void main(String[] args) {        String str  = "FUN FILMS FOR SUMMER-(3-1-A)-You'll smile" ;        System.out.println("原始：" + str) ;        System.out.println("结果：" + str.replace("'","\\'")) ;        }}
