java 常见api Arrays类

int类型数组

package daysreplace;import java.util.Arrays;public class Test {public static void main(String[] args) {int[] arrays={38,24,42,56,22,44};//直接输出数组名称就是内存地址System.out.println(arrays);//Arrays.toString()会将数组内容转成字符串形式System.out.println(Arrays.toString(arrays));Arrays.sort(arrays);System.out.println("排序后结果"+arrays);System.out.println("排序后结果从小到大"+Arrays.toString(arrays));System.out.println("排序后的结果从大到小");for (int i = arrays.length-1; i >=0 ; i--) {System.out.println(arrays[i]);}// System.out.println("排序后的结果从大到小"+Arrays.toString(arrays));}
}

char类型数组

package daysreplace;import java.util.Arrays;public class Test {public static void main(String[] args) {char[] ch={'a','c','b','m'};Arrays.sort(ch);System.out.println(Arrays.toString(ch));}
}
