接下来,我们将步骤3中创建的实例对象添加到List中: list.add(instance); 1. 步骤5:返回创建好的List对象 最后,我们返回创建好的List对象,即可完成整个过程: returnlist; 1. 代码示例 下面是完整的代码示例: importjava.lang.reflect.Constructor;importjava.util.ArrayList;importjava.util.List;publicclassCreateList...
使用Arrays.asList() Arrays.asList()方法可以将传入的参数转换为一个List对象。我们可以将参数写在Arrays.asList()方法的括号中,将其转换为一个List对象。这样就可以快速生成一个List了。 importjava.util.Arrays;importjava.util.List;publicclassMain{publicstaticvoidmain(String[]args){List<String>list=Arrays....
asList); 注:当调用Arrays.asList()时,它的返回值类型是ArrayList,但是这个ArrayList是Array的内部类别,当调用add()时,它会报错:java.lang.UnsupportedOperationException,结果会因array的某一值而改变,因此需要重新构建一个新的ArrayList。 3、使用Collections.addAll() 代码语言:javascript 代码运行次数:0 复制Cloud...
make mrproper make menuconfig make dep make clean make bzImage ……… 如果把这些命令做成一个文件,让它自动顺序执行,对于需要多次反复编译系统核心的用户来说会很方便,而用source命令就可以做到这一点,它的作用就是把一个文件的内容当成shell来执行, 先在linux的源代码目录下(如/usr/src/linux-2.4.20)建立...

List.stream().collect(Collectors.toMap(Emp::getId, a->a,(k1,k2)->k2))的意义是:将链表里的元素转成Map,Map的键取元素的id,值就取元素本身,当键同值不同时取后来者。 例程: Emp类: publicclassEmp {privateString id;privateString name;publicEmp(String id,String name) {this.id=id;this.name=...
