阅读下面的代码:publicclassExample{publicstaticvoidmain(String[]args){String[]strs={"Tom","Jerry","Donald"};//foreach循环遍历数组for(Stringstr:strs){str="Tuffy";}System.out.println(strs[0]+","+strs[1]+","+strs[2]);}}程序的运行结果是()
A: Tom,Jerry
B: Tom,Jerry,Tuffy
C: Tom,Jerry,Donald
D: 以上都不对
A: Tom,Jerry
B: Tom,Jerry,Tuffy
C: Tom,Jerry,Donald
D: 以上都不对
举一反三
- 阅读下面的程序public class Example{ public static void main(String[] args) { String[] strs = { "Tom", "Jerry", "Donald" }; // foreach循环遍历数组 for (String str : strs) { str = "Tuffy"; } System.out.println(strs[0] + "," + strs[1] + "," + strs[2]); }}程序的运行结果是( ) A: Tom,Jerry,Donald B: Tuffy,Jerry,Donald C: Tuffy, Tuffy, Tuffy D: 发生异常,输出异常信息
- public class Example{ public static void main(String[] args) { String[] strs = { "Tom", "Jerry", "Donald" }; // foreach循环遍历数组 for (String str : strs) { str = "Tuffy"; } System.out.println(strs[0] + "," + strs[1] + "," + strs[2]); } } 下列选项中,程序的运行结果是
- 中国大学MOOC: 如果有以下的程序代码:String[] [] strs {{Java,Java,Java},{Java,Java,Java,Java}System.out.println(strs.length) ; System.out.println(strs[0].length);System.out.print1n(strs[1].length);以下描述何者正确?
- 如果有以下关于String[][]的程序代码: String[][] strs = new String[2][5]; 以下描述正确的是( )
- 如果有以下的程序代码: String[] [] strs { {"Java","Java","Java"}, {"Java","Java","Java","Java"} System.out.println(strs.length) ; System.out.println(strs[0].length); System.out.print1n(strs[1].length); 以下描述何者正确? A: 显示2、3、4 B: 显示2、0、1 C: 显示1、2、3 D: 编译失败
