Java String equalsIgnoreCase()
方法將此字串與指定的物件進行比較並忽略大小寫。如果它們具有相同的長度,並且兩個字串中的相應字元等於忽略大小寫,則結果返回:true
,否則返回:false
。
語法
以下是此方法的語法 -
public boolean equalsIgnoreCase(String anotherString)
anObject
- 用於與此String進行比較的String。String
引數值忽略大小寫比較相等時,則此方法返回true
; 否則返回false
。public class Test {
public static void main(String args[]) {
String Str1 = new String("This is really not immutable!!");
String Str2 = Str1;
String Str3 = new String("This is really not immutable!!");
String Str4 = new String("This IS REALLY NOT IMMUTABLE!!");
boolean retVal;
retVal = Str1.equals( Str2 );
System.out.println("Returned Value = " + retVal );
retVal = Str1.equals( Str3 );
System.out.println("Returned Value = " + retVal );
retVal = Str1.equalsIgnoreCase( Str4 );
System.out.println("Returned Value = " + retVal );
}
}
執行上面範例程式碼,得到以下結果:
Returned Value = true
Returned Value = true
Returned Value = true
