java.text.Collator类的equals()方法用于检查两个字符串是否相同。
用法:
public boolean equals(String source, String target)
参数:此方法需要两个字符串之间进行比较。
返回值:如果两个字符串彼此相等,则返回true,否则返回false。
下面是说明equals()方法的示例:
范例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
// Collator Object
Collator col = Collator.getInstance();
// Creating an initializing
// object for comparison
String obj1 = "a";
// Creating an initializing
// Object for comparison
String obj2 = "A";
// compare both object
// using equals() mehtod
boolean i = col.equals(obj1, obj2);
// display result
if (i)
System.out.println(obj1
+ " is equal to "
+ obj2);
else
System.out.println(obj1
+ " is not equal to "
+ obj2);
}
catch (ClassCastException e) {
System.out.println("Exception thrown:" + e);
}
}
}
输出:
a is not equal to A
范例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
// Collator Object
Collator col = Collator.getInstance();
// Creating an initializing
// object for comparison
String obj1 = "a";
// Creating an initializing
// Object for comparison
String obj2 = "a";
// compare both object
// using equals() mehtod
boolean i = col.equals(obj1, obj2);
// display result
if (i)
System.out.println(obj1
+ " is equal to "
+ obj2);
else
System.out.println(obj1
+ " is not equal to "
+ obj2);
}
catch (ClassCastException e) {
System.out.println("Exception thrown:" + e);
}
}
}
输出:
a is equal to a
