使用数组
package example;import java.util.Arrays;public class UsingArrays {public static void output(int[] array){if(array != null){for(int i=0;i<array.length;i++){System.out.print(array[i]+ " ");}}System.out.println();}public static void main(String[] args){int[] array0 = new int[5];Arrays.fill(array0,5);System.out.println("调用Arrays.fill(array0,5)后：");UsingArrays.output(array0);Arrays.fill(array0, 2,4,8);System.out.println("调用Arrays.fill(array0,2,3,8)后：");UsingArrays.output(array0);int[] array1 = new int[]{7,8,3,12,6,3,5,4};Arrays.sort(array1, 2, 7);System.out.println("调用Arrays.sort(ayyay1,2,7)后：");UsingArrays.output(array1);Arrays.sort(array1);System.out.println("调用Arrays.sort(array1)后：");UsingArrays.output(array1);//System.out.println("array0和array1是否相等？");System.out.println(Arrays.equals(array0, array1));int[] array2 = (int[])array1.clone();System.out.println("array1和array2是否相等？"+Arrays.equals(array1, array2));}}?
