Java中的 String 类 stripTrailing() 方法及示例

此方法用于从字符串中去除尾随空格，即stripTrailing()方法仅删除字符串末尾的所有空格。

例子：

Input:

String name = "   kapil   ";
System.out.println("#" + name + "#);
System.out.println("#" + name.stripLeading());


Output:

#   kapil   #
#   kapil# // trailing whitespaces are removed 

句法：

public String stripTrailing()

参数：它不接受任何参数。

返回：去除字符串末尾所有空格后的字符串。

Note: Like the stripTrailing() method in java, we have strip() (removes leading and trailing whitespace) and stripLeading() (removes the only leading whitespace). 

Java

// Java program to demonstrate the usage of
// stripTrailing() method in comparison to 
// other methods
  
class GFG {
    public static void main(String[] args)
    {
  
        // creating a string
        String str = "  Hello,  World ";
  
        // print the string without any function
        System.out.println("String is");
        System.out.println("#" + str + "#");
        System.out.println();
  
        // using strip() method
        System.out.println("Using strip()");
        System.out.println("#" + str.strip() + "#");
        System.out.println();
  
        // using stripLeading() method
        System.out.println("Using stripLeading()");
        System.out.println("#" + str.stripLeading() + "#");
        System.out.println();
  
        // using stripTrailing() method
        System.out.println("Using stripTrailing()");
        System.out.println("#" + str.stripTrailing() + "#");
    }
}

输出

String is
#  Hello,  World #

Using strip()
#Hello,  World#

Using stripLeading()
#Hello,  World #

Using stripTrailing()
#  Hello,  World#
