可以使用 Java 8 引入的 stream API 来打印二维数组的行和列。以下是实现该方法的代码: int[][]arr={{1,2,3},{4,5,6},{7,8,9}};// 打印每行的元素Arrays.stream(arr).forEach(a->{System.out.print("Row "+Arrays.asList(arr).indexOf(a)+": ");Arrays.stream(a).forEach(e->System....
In Java 8, we can use Stream APIs to convert a simple array into a stream and print it out one by one; for 2d or nested array, we need to useflatMap. PrintArray2.java packagecom.mkyong;importjava.util.Arrays;publicclassPrintArray2{publicstaticvoidmain(String[] args){// simple arrayStr...
