JAVA中如何用replace函数把双引号替换成单引号

请各位兄弟帮帮忙呀

str.replace('\"','\');
或str.replaceAll("\"","\'");

str = str.replaceAll("\"","\'");//这样正解
str.replaceAll("\"","\'");//replaceAll()没有返回void的重载,为什么这里编译运行没错

str = str.replaceAll("\"","\'");

str = str.replaceAll("\"","\'");

Answer 6

replaceAll才对
str = str.replaceAll("\"","\'");

str = str.replaceAll("\"","\'");

str = str.replaceAll("\"","\'");
