  Why should the first letter of a Java class be upper-cased? Is it not possible to run a program containing lower-cased class names? If it is possible, what’s the difference?

  jquery uppercase lowercase
  I want a string to randomly alternate uppercase and lowercase letters.To do this I grab the content of class “post__title” into a string, explode that string into an array of letters. Then loop that array and randomly assign either 0 or 1 to each letter. If the value is 1, the letter should be transformed to uppercase, if the value is 0, the letter should be transformed to lower case. This then has to be reapplied to “post__title” replacing the old content.I’m quite inexperienced, but so far I h

  javascript string lowercase
  This is all the code I have:var ans = 334; var temp = ans.toLowerCase(); alert(temp);And then it gives me this error:’undefined’ is not a function (evaluating ‘ans.toLowerCase()’)I don’t know where I got this wrong. I always thought that numbers can also be parsed, with no change in result (maybe that’s where I stuffed up).But if that’s not the error, can someone write a custom makeLowerCase function, to make the string lower case, perhaps using regex or something?
