How to use java to concatenate strings

1. The Java language allows the use of symbols to connect (splice) two strings.

2. When a string is concatenated with a non-empty string value, the latter will be converted into a string (any Java object can be converted into a string).

Example

int age = 13;
String rating = "PG" + age;  //将rating设置为 "PG13"
 
//使用静态的 join 方法可以把多个字符串放在一起
//并指定一个界定符分隔
String all = String.join("/","S","M","L","XL");  //all的值为 S/M/L/XL
 
//repeated的值为 javajavajava
String repeated = "java".repeat(3);
