Java中打印數(shù)組時不想用for遍歷數(shù)組，可以試試下面幾種方法
https://foreti.me/2018/01/27/java-print-array/
ArrayList直接打印
ArrayList<Integer> list = new ArrayList<>();
list.add(1);
list.add(2);
list.add(3);
list.add(4);
System.out.println(list);
輸出
[1, 2, 3, 4]
Arrays類打印數(shù)組
java.util.Arrays的toString()方法
System.out.println(Arrays.toString(new int[] {1, 2, 3, 4}));
輸出
[1, 2, 3, 4]
Arrays類打印二維數(shù)組
java.util.Arrays的deeptoString()方法
System.out.println(Arrays.deepToString(new int[][] {{1, 2}, {3, 4}}));
輸出
[[1, 2], [3, 4]]
