參數：

S::抽象字符串：指定字符串
我::整數：包含起始位置。
我::整數：包含結束位置。

返回值：它返回具有所需起始和結束位置的指定字符串的長度。

範例1：


# Julia program to illustrate 
# the use of String length() method
  
# Finding the length of the string
# "Geeks"
println(length("Geeks"))
  
# Finding the length of the string
# "Geeks" from 2nd to 4th position
println(length("Geeks", 2, 4))
  
# Finding the length of the string
# "Geeks" from 2nd to 5th position
println(length("Geeks", 2, 5))
  
# Finding the length of the string
# "GeeksforGeeks" 
println(length("GeeksforGeeks"))
  
# Finding the length of the string
# "GeeksforGeeks" from 2nd to 2nd position
println(length("GeeksforGeeks", 2, 2))
  
# Finding the length of the string
# "GeeksforGeeks" from 4th to 10th position
println(length("GeeksforGeeks", 4, 10))

輸出：

範例2：


# Julia program to illustrate 
# the use of String length() method
   
# Finding the length of the string
# "12345"
