字符串文字和字符文字可以连接吗？

string_literal = "Hello"
char_literal = 'W'
result = string_literal + char_literal
print(result)  # 输出 "HelloW"

String stringLiteral = "Hello";
char charLiteral = 'W';
String result = stringLiteral.concat(String.valueOf(charLiteral));
System.out.println(result);  // 输出 "HelloW"

let stringLiteral = "Hello";
let charLiteral = 'W';
let result = stringLiteral + charLiteral;
console.log(result);  // 输出 "HelloW"
