将以上步骤整合到一个Java程序中,如下所示: publicclassFindCharacterInString{publicstaticvoidmain(String[]args){Stringstr="Hello, World!";// 定义字符串charch='o';// 定义要查找的字符intindex=str.indexOf(ch);// 使用indexOf()查找字符if(index!=-1){System.out.println("字符 '"+ch+"' 在字符...

1. Using Plain Java Let us start with writing the program logic ourselves. In this solution, we are creatingMapwhere each unique character in the string is theMapkey, and the number of occurrences of the character is stored as the value. 1.1. Algorithm Split the string into a character ar...
