方法sort（int [] a，int fromIndex，int toIndex）在Java中做什么？
java.util.Arrays类的 sort（int[]a，intfromIndex，inttoIndex）方法将指定整数值数组的指定范围按升序排序。要排序的范围从索引fromIndex（包括）到索引toIndex（不包括）。
示例
import java.util.Arrays;
public class ArrayDemo {
public static void main(String[] args) {
int iArr[] = {3, 1, 2, 18, 10};
for (int number : iArr) {
System.out.println("Number = " + number);
}
Arrays.sort(iArr, 0, 3);
System.out.println("int array with some sorted values(0 to 3) is:");
for (int number : iArr) {
System.out.println("Number = " + number);
}
}
}输出结果
Number = 3 Number = 1 Number = 2 Number = 18 Number = 10 int array with some sorted values(0 to 3) is: Number = 1 Number = 2 Number = 3 Number = 18 Number = 10
