将字符串元素赋值给变量

# 单引号字符串
single_quoted_string = 'Hello, World!'

# 双引号字符串
double_quoted_string = "Hello, World!"

print(single_quoted_string)
print(double_quoted_string)

// 单引号字符串
let singleQuotedString = 'Hello, World!';

// 双引号字符串
let doubleQuotedString = "Hello, World!";

console.log(singleQuotedString);
console.log(doubleQuotedString);

// 双引号字符串
String doubleQuotedString = "Hello, World!";

// 单引号字符串（Java中单引号用于字符）
char singleQuotedChar = 'A';

System.out.println(doubleQuotedString);
System.out.println(singleQuotedChar);

# 使用转义字符
escaped_string = "He said, \"Hello, World!\""

# 使用模板字符串（Python 3.6+）
template_string = f"He said, 'Hello, World!'"

# 使用 join 方法
strings = ['Hello', 'World']
result = ' '.join(strings)
print(result)

# Java 中使用 StringBuilder
StringBuilder sb = new StringBuilder();
sb.append("Hello");
sb.append(" ");
sb.append("World");
String result = sb.toString();
System.out.println(result);
