Java ParsePosition getIndex()用法及代码示例


java.text.ParsePosition类的getIndex()方法用于检索此ParsePositon对象的当前解析位置。

用法:

public int getIndex()

参数:此方法不接受任何参数作为参数。


返回值:此方法返回此解析位置对象的当前解析位置。

下面是说明getIndex()方法的示例:

范例1:

// Java program to demonstrate 
// getIndex() method 
  
import java.text.*; 
import java.util.*; 
import java.io.*; 
  
public class GFG { 
    public static void main(String[] argv) 
    { 
        try { 
  
            // Creating and initializing 
            // new ParsePosition Object 
            ParsePosition pos 
                = new ParsePosition(1); 
  
            // set index for the parsing error 
            pos.setErrorIndex(3); 
  
            // getting the current 
            // ParsePosition of 
            // using getIndex() method 
            int i = pos.getIndex(); 
  
            // display result 
            System.out.println( 
                "current parse position:"
                + Integer.toString(i)); 
        } 
  
        catch (ClassCastException e) { 
  
            System.out.println(e); 
        } 
    } 
}
输出:
current parse position:1

范例2:

// Java program to demonstrate 
// getIndex() method 
  
import java.text.*; 
import java.util.*; 
import java.io.*; 
  
public class GFG { 
    public static void main(String[] argv) 
    { 
        try { 
  
            // Creating and initializing 
            // new ParsePosition Object 
            ParsePosition pos 
                = new ParsePosition(1); 
  
            // set index for current 
            // Parse Position 
            pos.setIndex(3); 
  
            // getting the current 
            // ParsePosition of 
            // using getIndex() method 
            int i = pos.getIndex(); 
  
            // display result 
            System.out.println( 
                "current parse position:"
                + Integer.toString(i)); 
        } 
  
        catch (ClassCastException e) { 
  
            System.out.println(e); 
        } 
    } 
}
输出:
current parse position:3
