Guava庫中Shorts類的lastIndexOf()方法用於在short數組中查找給定short值的最後一個索引。要搜索的short值和要在其中搜索的short數組都作為參數傳遞給此方法。它返回一個整數值,該整數值是指定的short值的最後一個索引。如果找不到該值,則返回-1。
用法:
public static int lastIndexOf(short[] array, short target)
參數:此方法接受兩個強製性參數:
- array:這是在其中搜索短值的短值數組。
- target:這是在short數組中要搜索的最後一個索引的short值。
返回值:此方法返回一個整數值,該整數值是指定的short值的最後一個索引。如果找不到該值,則返回-1。
下麵的程序演示了此方法:
範例1:
// Java code to show implementation of
// Guava's Shorts.lastIndexOf() method
import com.google.common.primitives.Shorts;
import java.util.Arrays;
class GFG {
// Driver's code
public static void main(String[] args)
{
// Creating a short array
short[] arr = { 1, 2, 3, 4, 3, 5, 3, 4 };
short target = 3;
// Using Shorts.lastIndexOf() method
// to get the index of last appearance
// of a given element in array
// and return -1 if element is
// not found in the array
int index
= Shorts.lastIndexOf(arr, target);
if (index != -1) {
System.out.println("Target is present"
+ " at index "
+ index);
}
else {
System.out.println("Target is not present"
+ " in the array");
}
}
}
輸出:
Target is present at index 6
範例2:
// Java code to show implementation of
// Guava's Shorts.lastIndexOf() method
import com.google.common.primitives.Shorts;
import java.util.Arrays;
class GFG {
// Driver's code
public static void main(String[] args)
{
// Creating a short array
short[] arr = { 3, 5, 7, 11, 13 };
short target = 17;
// Using Shorts.lastIndexOf() method
// to get the index of last appearance
// of a given element in array
// and return -1 if element is
// not found in the array
int index
= Shorts.lastIndexOf(arr, target);
if (index != -1) {
System.out.println("Target is present"
+ " at index "
+ index);
}
else {
System.out.println("Target is not present"
+ " in the array");
}
}
}
輸出:
Target is not present in the array
