Java中如何高效地更改或自定义代码格式化风格？

Java中格式化字符串的方法有很多,以下是一些常用的格式化方法：

使用String.format()方法

String.format()方法可以用于格式化字符串，它允许你插入变量并按照指定的格式进行显示,以下是一个简单的例子：

public class Main { public static void main(String[] args) { int age = 25; String name = "张三"; String result = String.format("我叫%s，今年%d岁。", name, age); System.out.println(result); } }

输出结果为：

我叫张三，今年25岁。

使用System.out.printf()方法

System.out.printf()方法与String.format()方法类似，但它直接输出到控制台,以下是一个例子：

public class Main { public static void main(String[] args) { int age = 25; String name = "李四"; System.out.printf("我叫%s，今年%d岁，n", name, age); } }

输出结果为：

我叫李四，今年25岁。

使用格式化字符串插值

从Java 14开始，引入了新的格式化字符串插值语法，允许你在字符串中使用来插入变量,以下是一个例子：

public class Main { public static void main(String[] args) { int age = 25; String name = "王五"; String result = String.format("我叫%s，今年%d岁。", name, age); System.out.println(result); String result2 = String.format("我叫%s，今年%d岁。", name, age); System.out.println(result2); String result3 = String.format("我叫%s，今年%d岁。", name, age); System.out.println(result3); String result4 = String.format("我叫%s，今年%d岁。", name, age); System.out.println(result4); String result5 = String.format("我叫%s，今年%d岁。", name, age); System.out.println(result5); String result6 = String.format("我叫%s，今年%d岁。", name, age); System.out.println(result6); String result7 = String.format("我叫%s，今年%d岁。", name, age); System.out.println(result7); String result8 = String.format("我叫%s，今年%d岁。", name, age); System.out.println(result8); String result9 = String.format("我叫%s，今年%d岁。", name, age); System.out.println(result9); String result10 = String.format("我叫%s，今年%d岁。", name, age); System.out.println(result10); String result11 = String.format("我叫%s，今年%d岁。", name, age); System.out.println(result11); String result12 = String.format("我叫%s，今年%d岁。", name, age); System.out.println(result12); String result13 = String.format("我叫%s，今年%d岁。", name, age); System.out.println(result13); String result14 = String.format("我叫%s，今年%d岁。", name, age); System.out.println(result14); String result15 = String.format("我叫%s，今年%d岁。", name, age); System.out.println(result15); String result16 = String.format("我叫%s，今年%d岁。", name, age); System.out.println(result16); String result17 = String.format("我叫%s，今年%d岁。", name, age);
