Java JavaTuples containsAll()用法及代碼示例

org.javatuples中的containsAll()方法用於檢查在TupleClass中是否存在作為參數給出的值的集合。此方法可用於javatuples庫的任何tuple類對象。根據TupleClass中該值集合的存在，它返回一個布爾值，該布爾值是true還是false。

方法聲明：

public final boolean containsAll(Object... value)

用法:

boolean result = TupleClassObject.containsAll(X value1, X value2, ...)
                    OR
boolean result = TupleClassObject.containsAll(X[] values)

參數：此方法將一個或多個值作為參數，其中：

X-表示參數中值的數據類型。
TupleClassObject-表示JavaTuple Class對象，例如Unit，Quintet，Decade等。

返回值：如果元組中存在參數值，則此方法返回true。否則返回假

以下示例程序旨在說明使用containsAll()方法的各種方法：

程序1:使用containsAll()和Unit類：

// Below is a Java program to use containsAll() method 
  
import java.util.*; 
import org.javatuples.Unit; 
  
class GfG { 
    public static void main(String[] args) 
    { 
        // Creating an Unit with one value 
        Unit<String> unit = Unit.with("GeeksforGeeks"); 
  
        // Using containsAll() method 
  
        boolean res; 
  
        // for True result 
        String[] check = { "GeeksforGeeks" }; 
        res = unit.containsAll(check); 
  
        System.out.println("Is " + Arrays.toString(check) + " present:" + res); 
  
        // for False result 
        String[] check1 = { "Geeks", "for", "Geeks" }; 
        res = unit.containsAll(check1); 
  
        System.out.println("Is " + Arrays.toString(check1) + " present:" + res); 
    } 
}

輸出：

Is [GeeksforGeeks] present:true
Is [Geeks, for, Geeks] present:false

程序2:將containsAll()與Decade類一起使用：

// Below is a Java program to use containsAll() method 
  
import java.util.*; 
import org.javatuples.Decade; 
  
class GfG { 
    public static void main(String[] args) 
    { 
        // Creating a Decade with 10 value 
        Decade<String, String, String, String, String, 
               String, String, String, String, String> 
            decade = Decade.with("Geeks", 
                                 "for", 
                                 "Geeks", 
                                 "A", 
                                 "Computer", 
                                 "Science", 
                                 "Portal", 
                                 "for", 
                                 "Geeks", 
                                 "RishabhPrabhu"); 
  
        // Using containsAll() method 
        boolean res; 
  
        // for true result 
        String[] check = { "Geeks", "for", "Geeks" }; 
        res = decade.containsAll(check); 
  
        System.out.println("Is " + Arrays.toString(check) + " present:" + res); 
  
        // for False result 
        String[] check1 = { "Geeks", "not", "for", "Geeks" }; 
        res = decade.containsAll(check1); 
  
        System.out.println("Is " + Arrays.toString(check1) + " present:" + res); 
    } 
}

輸出：

Is [Geeks, for, Geeks] present:true
Is [Geeks, not, for, Geeks] present:false

注意：同樣，它可以與任何其他JavaTuple類一起使用。
