Java中用forEach和lamad优化for循环

 1 import java.util.Arrays;
 2 import java.util.List;
 3 import java.util.function.IntBinaryOperator;

 5 
 6 List<String> names = Arrays.asList("Alice", "Bob", "Charlie");
 7 
 8 // 方式一for输出
 9 for (int i = 0; i < names.size(); i++) {
10             if(name.equals("Bob")){
11             System.out.println("\"dier\" = " + "dier");
12 }
13 
14 // 方式二forEach输出
15 names.forEach(name ->
16         {
17             if(name.equals("Bob")){
18             System.out.println("\"dier\" = " + "dier");
19         }
20 });
21     
22 //补充，只执行一条语法
23 names.forEach(name -> System.out.println(name));
