Since both arrays have identical elements in the same order, the method returns true. Example 2: Comparing Character Arrays import java.util.Arrays; public class CharArrayEqualsExample { public static void main(String[] args) { char[] array1 = {'a', 'b', 'c'}; char[] array2 = {'...
复制数组:System.arraycopy(arrayA,a,arrayB,b,c):从arrayA中的第a元素开始复制c个元素到从第b个元素开始的arrayB. 比较两个数组的数据是否相等:Array.equals(arrayA,arrayB):两数组相等则返回true.需要引入包:java.util.Arrays 搜索数组中的元素位置:int i=binarySearch(ayyayA,Str):搜索arrayA数组中的字符...
