您可以使用concat ()方法或使用“ +”(“连接”运算符)来连接Java中的两个字符串。
public class ConncatSample { public static void main(String []args) { String s1 = "Hello"; String s2 = "world"; String res1 = s1.concat(s2); String res2 = s1+s2; System.out.print("Concatenation using method:: "); System.out.println(res1); System.out.print("Concatenation using operator:: "); System.out.println(res2); } }
Concatenation using method:: Helloworld Concatenation using operator:: Helloworld
