Java String stripLeading()用法及代码示例

字符串类stripLeading()方法用于从字符串中去除前导空格，即stripLeading()方法仅在字符串的开头删除所有空格。

例：

Input:

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


Output:

#   kapil   #
#kapil   # // Leading whitespaces are removed

用法:

public String stripLeading()

返回值：删除字符串开头的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).

下面是问题陈述的实现：

Java

// Java program to demonstrate the usage of 
// stripLeading() 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#
