想要从 String 数组中替换 WhiteSpace
Want to replace WhiteSpace from array of String
private static final String SQL_INSERT = "INSERT INTO ${table}(${keys}) VALUES(${values})";
private static final String SQL_CREATE = "CREATE TABLE ${table}(${keys} VARCHAR(20) NOT NULL)";
private static final String TABLE_REGEX = "\$\{table\}";
private static final String KEYS_REGEX = "\$\{keys\}";
private static final String VALUES_REGEX = "\$\{values\}";
String[] headerRow = csvReader.readNext();//getting(Machine Name , Value)
String[] stripedHeaderRow = StringUtils.stripAll(headerRow);
String query2 = SQL_CREATE.replaceFirst(TABLE_REGEX, tableName);
query2 = query2.replaceFirst(KEYS_REGEX, StringUtils.join(headerRow, " VARCHAR(20) NOT NULL,"));
结果:
"Machine Name, Value"
预期结果:
"MachineName , Value"
您可以在 JAVA 中使用正则表达式来完成。
例如:
String a = "Hello World!!";
a = a.replaceAll("\s","");
现在的价值a = "HelloWorld!!"
假设您的数组在 temp
变量中,
以下是如何修剪每个字符串之间的所有空格。
String[] temp = {"My Name Is", "And so Far", "All good", "Really?",
"That makes no sense to me", "Oh! Somehthing Like This"};
Stream<String> stream = Arrays.stream(temp);
temp = stream.map(str -> str.replaceAll("\s",""))
.toArray(size -> new String[size]);
现在如果打印它,它会给出这个..
for(String st : temp)
System.out.println(st);
输出:-
MyNameIs
AndsoFar
Allgood
Really?

Oh!SomehthingLikeThis
我创建了 arrayList 来修改 String 内容的数组,
List<String> al = new ArrayList<String>();
for (String element: headerRow)
{
al.add(element.replace(' ', '_'));
}
String[] stripedHeaderRow = al.toArray(new String[al.size()]);//Creating new array of String
//这将满足我的结果。
private static final String SQL_INSERT = "INSERT INTO ${table}(${keys}) VALUES(${values})";
private static final String SQL_CREATE = "CREATE TABLE ${table}(${keys} VARCHAR(20) NOT NULL)";
private static final String TABLE_REGEX = "\$\{table\}";
private static final String KEYS_REGEX = "\$\{keys\}";
private static final String VALUES_REGEX = "\$\{values\}";
String[] headerRow = csvReader.readNext();//getting(Machine Name , Value)
String[] stripedHeaderRow = StringUtils.stripAll(headerRow);
String query2 = SQL_CREATE.replaceFirst(TABLE_REGEX, tableName);
query2 = query2.replaceFirst(KEYS_REGEX, StringUtils.join(headerRow, " VARCHAR(20) NOT NULL,"));
