Java Guava Splitter limit()用法及代碼示例

方法limit(int limit)返回一個行為與該拆分器等效的拆分器，但在達到限製後停止拆分。該限製定義了迭代器返回的最大項目數，或splitToList(java.lang.CharSequence)返回的列表的最大大小。例如，Splitter.on(’，).limit(3).split(“ a，b，c，d”)返回包含[“a”，“b”，“ c，d”]的可迭代項。

用法:

public Splitter limit(int limit)

參數：此方法將limit作為參數，該參數是要返回的最大項目數。

返回值：此方法返回具有所需配置的拆分器。

範例1：

// Java code to show implementation of 
// limit(int limit) method 
// of Guava's Splitter Class 
  
import com.google.common.base.Splitter; 
import java.util.List; 
  
class GFG { 
  
    // Driver's code 
    public static void main(String[] args) 
    { 
  
        // Creating a string variable 
        String str = "geeks, .  for, .Hey.,  "
                     + "geeks, ., noida, ., classes"; 
  
        // Initially setting limit as 3 
        System.out.println("When Limit is 3:"); 
  
        // Using limit(int limit) method which 
        // stops splitting after it reaches the limit. 
        Iterable<String> result = Splitter.on(',') 
                                      .limit(3) 
                                      .trimResults() 
                                      .split(str); 
        for (String temp:result) { 
            System.out.println(temp); 
        } 
  
        // Setting limit as 4 
        System.out.println("\n\nWhen Limit is 4:"); 
  
        // Using limit(int limit) method which 
        // stops splitting after it reaches the limit. 
        Iterable<String> result1 = Splitter.on(',') 
                                       .limit(4) 
                                       .trimResults() 
                                       .split(str); 
        for (String temp:result1) { 
            System.out.println(temp); 
        } 
    } 
}

輸出：

When Limit is 3:
geeks
.  for
.Hey.,  geeks, ., noida, ., classes


When Limit is 4:
geeks
.  for
.Hey.
geeks, ., noida, ., classes

範例2：

// Java code to show implementation of 
// limit(int limit) method 
// of Guava's Splitter Class 
  
import com.google.common.base.Splitter; 
import java.util.List; 
  
class GFG { 
  
    // Driver's code 
    public static void main(String[] args) 
    { 
  
        // Creating a string variable 
        String str = "Learn$,,Data $ structures"
                     + " 123$ to be $ best Coder.."; 
  
        // Initially setting limit as 2 
        System.out.println("When Limit is 2:"); 
  
        // Using limit(int limit) method which 
        // stops splitting after it reaches the limit. 
        Iterable<String> result = Splitter.on('$') 
                                      .limit(2) 
                                      .trimResults() 
                                      .split(str); 
        for (String temp:result) { 
            System.out.println(temp); 
        } 
  
        // Setting limit as 4 
        System.out.println("\n\nWhen Limit is 4:"); 
  
        // Using limit(int limit) method which 
        // stops splitting after it reaches the limit. 
        Iterable<String> result1 = Splitter.on('$') 
                                       .limit(4) 
                                       .trimResults() 
                                       .split(str); 
        for (String temp:result1) { 
            System.out.println(temp); 
        } 
    } 
}

輸出：

When Limit is 2:
Learn,,Data $ structures 123$ to be $ best Coder..


When Limit is 4:
Learn,,Data
structures 123
to be $ best Coder..

注意：

省略空字符串時，省略的字符串不計算在內。因此，Splitter.on('，).limit(3).omitEmptyStrings().split(“ a ,,, b ,, c，d”)返回包含[“a”，“b”，“ c，d”]的可迭代對象。
當請求修剪時，所有條目(包括最後一個條目)都會被修剪。因此，Splitter.on('，).limit(3).trimResults().split(“ a，b，c，d”)的結果為[“a”，“b”，“ c，d”]。
