解析位置等于()方法在 Java 中的示例
原文:https://www . geeksforgeeks . org/parse position-equals-method-in-Java-with-example/
java.text.ParsePosition 类的 equals() 方法用于检查两个 ParsePosition 对象是否相同。
语法:
public boolean equals(Object obj)
参数:该方法取 ParsePosition 对象，与当前 ParsePosition 对象进行比较。
返回值:如果两个解析位置对象彼此相等，则返回真，否则返回假。
以下是说明等于()方法的示例:
例 1:
// Java program to demonstrate
// equals() 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_1
= new ParsePosition(0);
// Creating and initializing
// new ParsePosition Object
ParsePosition pos_2
= new ParsePosition(0);
// compare both object
// using equals() mehtod
boolean i = pos_1.equals(pos_2);
// display result
if (i)
System.out.println(
"pos_1 is equals to pos_2");
else
System.out.println(
"pos_1 is not equal to pos_2");
}
catch (ClassCastException e) {
System.out.println(e);
}
}
}
输出:
pos_1 is equals to pos_2
例 2:
// Java program to demonstrate
// equals() 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_1
= new ParsePosition(0);
// Creating and initializing
// new ParsePosition Object
ParsePosition pos_2
= new ParsePosition(1);
// compare both object
// using equals() mehtod
boolean i = pos_1.equals(pos_2);
// display result
if (i)
System.out.println(
"pos_1 is equals to pos_2");
else
System.out.println(
"pos_1 is not equal to pos_2");
}
catch (ClassCastException e) {
System.out.println(e);
}
}
}
输出:
pos_1 is not equal to pos_2
