下面是完整的示例代码,展示了如何使用replaceAll()函数实现多个字符的替换: publicclassReplaceMultipleCharacters{publicstaticvoidmain(String[]args){Stringstr="Hello, World!";char[]charArray=str.toCharArray();for(inti=0;i<charArray.length;i++){if(charArray[i]=='o'){charArray[i]='a';}}Stringnew...
假设我们有一个字符串str,其中包含多个连续的相同字符,我们想将这些连续的相同字符替换为一个字符。 以下是一个使用replaceAll()方法替换多个字符为一个字符的示例代码: publicclassReplaceExample{publicstaticvoidmain(String[]args){Stringstr="Helloooo world!!";StringnewStr=str.replaceAll("(.)\\1+","$1")...
