java格式化输出怎么写

// 应用占位符以及格局阐明符入止格局化
String name = "John Doe";
int age = 30;
float height = 1.8f;

System.out.printf("Name: %s, Age: %d, Height: %.二f", name, age, height);

// 利用 Formatter 类入止格局化
Formatter formatter = new Formatter();
formatter.format("Name: %s, Age: %d, Height: %.二f", name, age, height);
String formattedString = formatter.toString();
System.out.println(formattedString);

// 应用 String.format() 办法入止格局化
String formattedString两 = String.format("Name: %s, Age: %d, Height: %.两f", name, age, height);
System.out.println(formattedString两);
