如何将字符串转换为格式化字符串？

name = "Alice"
age = 25
formatted_string = "My name is {} and I am {} years old.".format(name, age)
print(formatted_string)

My name is Alice and I am 25 years old.

String name = "Alice";
int age = 25;
String formattedString = String.format("My name is %s and I am %d years old.", name, age);
System.out.println(formattedString);

My name is Alice and I am 25 years old.
