java.text.ParsePosition类的getErrorIndex()方法用于检索可能发生解析错误的索引。
用法:
public int getErrorIndex()
参数:此方法不接受任何参数作为参数。
返回值:此方法返回可能发生解析错误的索引。
下面是说明getErrorIndex()方法的示例:
范例1:
// Java program to demonstrate
// getErrorIndex() 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(0);
// set index for the parsing error
pos.setErrorIndex(3);
// getting index at which
// parsing error may come
// using getErrorIndex() method
int i = pos.getErrorIndex();
// display result
System.out.println(
"index at which parse error may occur:"
+ Integer.toString(i));
}
catch (ClassCastException e) {
System.out.println(e);
}
}
}
输出:
index at which parse error may occur:3
范例2:
// Java program to demonstrate
// getErrorIndex() 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(0);
// getting index at which
// parsing error may come
// using getErrorIndex() method
int i = pos.getErrorIndex();
// display result
if (i != -1)
System.out.println(
"index at which parse error may occur:"
+ Integer.toString(i));
else
System.out.println("error index is not set");
}
catch (ClassCastException e) {
System.out.println(e);
}
}
}
输出:
error index is not set
