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]); }}下列选项中,程序的运行结果是( )
A: A、Tom,Jerry,Donald
B: B、Tuffy,Jerry,Donald
C: C、Tuffy,Tuffy,Tuffy
D: D、发生异常,输出异常信息
A: A、Tom,Jerry,Donald
B: B、Tuffy,Jerry,Donald
C: C、Tuffy,Tuffy,Tuffy
D: D、发生异常,输出异常信息
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]); }}下列选项中,程序的运行结果是( ) A: A、Tom,Jerry,Donald B: B、Tuffy,Jerry,Donald C: C、Tuffy,Tuffy,Tuffy D: D、发生异常,输出异常信息
- 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]);}}下列选项中,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
- 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
- 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?
