I thought typecasting to char we do the trick but it just prints ascii values
String str = JOptionPane.showInputDialog("Enter a word");
str = str.toUpperCase();
String temp = "";
for(int i = 0 ; i < str.length() ; i++)
{
temp += (char)str.charAt(i) + 1;
}
System.out.println(temp);
Your mistake is you are adding integer 1 to char . This will return the ASCII code of the next char.
Change to
temp += (char)(str.charAt(i) +1)
您要加上+ 1,并导致将其转换为整数,我不确定是否正确解释了就将其删除
