Java virkne to LowerCase()

The java virkne to LowerCase() metode atgriež virkni ar mazajiem burtiem. Citiem vārdiem sakot, tas pārvērš visas virknes rakstzīmes mazajos burtos.

Metode toLowerCase() darbojas tāpat kā metode toLowerCase(Locale.getDefault()). Tā iekšēji izmanto noklusējuma lokalizāciju.

Iekšējā ieviešana

 public String toLowerCase(Locale locale) { if (locale == null) { throw new NullPointerException(); } int firstUpper; final int len = value.length; /* Now check if there are any characters that need to be changed. */ scan: { for (firstUpper = 0 ; firstUpper = Character.MIN_HIGH_SURROGATE) &amp;&amp; (c <= character.max_high_surrogate)) { int supplchar="codePointAt(firstUpper);" if (supplchar !="Character.toLowerCase(supplChar))" break scan; } firstupper +="Character.charCount(supplChar);" else (c firstupper++; return this; char[] result="new" char[len]; resultoffset="0;" * may grow, so i+resultoffset is the write location in just copy first few lowercase characters. system.arraycopy(value, 0, result, firstupper); string lang="locale.getLanguage();" boolean localedependent="(lang" =="tr" || 'az' 'lt'); lowerchararray; lowerchar; srcchar; srccount; for (int i="firstUpper;" <len; srcchar="(int)value[i];" ((char)srcchar>= Character.MIN_HIGH_SURROGATE &amp;&amp; (char)srcChar <= character.max_high_surrogate) { srcchar="codePointAt(i);" srccount="Character.charCount(srcChar);" } else if (localedependent || 'u03a3') greek capital letter sigma lowerchar="ConditionalSpecialCasing.toLowerCaseEx(this," i, locale); (srcchar="=" 'u0130') latin i dot ((lowerchar="=" character.error) (lowerchar>= Character.MIN_SUPPLEMENTARY_CODE_POINT)) { if (lowerChar == Character.ERROR) { if (!localeDependent &amp;&amp; srcChar == &apos;u0130&apos;) { lowerCharArray = ConditionalSpecialCasing.toLowerCaseCharArray(this, i, Locale.ENGLISH); } else { lowerCharArray = ConditionalSpecialCasing.toLowerCaseCharArray(this, i, locale); } } else if (srcCount == 2) { resultOffset += Character.toChars(lowerChar, result, i + resultOffset) - srcCount; continue; } else { lowerCharArray = Character.toChars(lowerChar); } /* Grow result if needed */ int mapLen = lowerCharArray.length; if (mapLen &gt; srcCount) { char[] result2 = new char[result.length + mapLen - srcCount]; System.arraycopy(result, 0, result2, 0, i + resultOffset); result = result2; } for (int x = 0; x <maplen; ++x) { result[i + resultoffset x]="lowerCharArray[x];" } - srccount); else resultoffset]="(char)lowerChar;" return new string(result, 0, len resultoffset); < pre> <h3>Signature</h3> <p>There are two variant of toLowerCase() method.

Otrais metodes toLowerCase() variants visas rakstzīmes pārvērš mazajos burtos, izmantojot dotās lokalizācijas noteikumus.

Java String to LowerCase(Locale locale) metodes 2. piemērs

Šī metode ļauj mums nodot lokalizāciju arī dažādām valodām. Tālāk ir sniegts piemērs, kur mēs iegūstam virkni gan angļu, gan turku valodā.

 import java.util.Locale; public class StringLowerExample2 { public static void main(String[] args) { String s = &apos;JAVATPOINT HELLO stRIng&apos;; String eng = s.toLowerCase(Locale.ENGLISH); System.out.println(eng); String turkish = s.toLowerCase(Locale.forLanguageTag(&apos;tr&apos;)); // It shows i without dot System.out.println(turkish); } }

Izvade:

 javatpoint hello string javatpo?nt hello str?ng
