拆分器 trimResults() 方法 |番石榴 |Java

方法trimResults()返回一个与此拆分器等效的拆分器，但会自动从每个返回的子字符串中删除前导和尾随空格。例如，
Splitter.on(', ').trimResults().split(” a, b, c “)返回一个包含[“a”, “b”, “c”]的可迭代对象。

句法：

public Splitter trimResults()

返回值：此方法返回具有所需配置的拆分器。

示例 1：

// Java code to show implementation of
// trimResults() 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 = "Hello,  geeks, for,  geeks,  noida";
  
        // Using trimResults() method. Strings that
        // have been split apart often need to be
        // trimmed. They often have surrounding whitespace.
        // With trimResults(), Splitter does this.
        List myList = Splitter.on(',')
          .trimResults().splitToList(str);
  
        for (String temp : myList) {
            System.out.println(temp);
        }
    }
}

输出：

Hello
geeks
for
geeks
noida
