[Java知识库]MessageFormat占位符使用

在开发过程中，我们经常需要将一个字符串插入这个字符串中间，到底插入那个位置呢？这时候占位符就派上用场了

import java.text.MessageFormat;
public class TestMessageFormat {
    public static void main(String[] args) {
        String str = "Package under internal review, type: {0}. Processing time: 3 business days";
        String [] person={"teather"};
        String string =MessageFormat.format(str , person);
        System.out.println(string);
    }
}

输出结果：Package under internal review, type: teather. Processing time: 3 business days

import java.text.MessageFormat;
public class TestMessageFormat {
    public static void main(String[] args) {
        String str = "Package under internal review, type: {0},{1}. Processing time: 3 business days";
        String [] person={"teather","student"};
        String string =MessageFormat.format(str , person);
        System.out.println(string);
    }
}

输出结果：Package under internal review, type: teather,student. Processing time: 3 business days
