运行"For loop“时跳过空格

string = "Hello World"
for char in string:
    if char == ' ':
        continue
    print(char)

const string = "Hello World";
const regex = /[^\s]/g;
const matches = string.match(regex);
for (let i = 0; i < matches.length; i++) {
    console.log(matches[i]);
}

String string = "Hello World";
String trimmedString = string.replace(" ", "");
for (int i = 0; i < trimmedString.length(); i++) {
    System.out.println(trimmedString.charAt(i));
}
