java实现查找替换功能

本文实例为大家分享了java实现查找替换功能的具体代码，供大家参考，具体内容如下

查找

if(searchTxt.getText().equals("")){

JOptionPane.showMessageDialog(null, "查找内容不能为空！");

}else if(!searchTxt.getText().equals("")){

//searchDialog.dispose();

if(fileChoose.focus == 1){

fileChoose.tp1.requestFocus(true);

str = fileChoose.tp1.getText();

startPosition = str.indexOf(searchTxt.getText());

endPosition = startPosition + searchTxt.getText().length();

fileChoose.tp1.select(startPosition, endPosition);

newEndPosition = endPosition;

}else if(fileChoose.focus == 2){

fileChoose.tp2.requestFocus(true);

str = fileChoose.tp2.getText();

startPosition = str.indexOf(searchTxt.getText());

endPosition = startPosition + searchTxt.getText().length();

fileChoose.tp2.select(startPosition, endPosition);

newEndPosition = endPosition;

}

}

查找下一处

nextTemp = newEndPosition;

if(fileChoose.focus == 1){

strAll = fileChoose.tp1.getText();

fileChoose.tp1.select(nextTemp, strAll.length());//选中所有未查找的字符串

nextStr = fileChoose.tp1.getSelectedText();

newStartPosition = nextStr.indexOf(searchTxt.getText()) + nextTemp;//在未查找的字符串中查找对应字符在tp1中的位置

newEndPosition = newStartPosition + searchTxt.getText().length();

fileChoose.tp1.select(newStartPosition, newEndPosition);//找到文本，选择文本

}else if(fileChoose.focus == 2){

strAll = fileChoose.tp2.getText();

fileChoose.tp2.select(nextTemp, strAll.length());//选中所有未查找的字符串

nextStr = fileChoose.tp2.getSelectedText();

newStartPosition = nextStr.indexOf(searchTxt.getText()) + nextTemp;//在未查找的字符串中查找对应字符在tp1中的位置

newEndPosition = newStartPosition + searchTxt.getText().length();

fileChoose.tp2.select(newStartPosition, newEndPosition);//找到文本，选择文本

}

替换

if(fileChoose.focus == 1){

fileChoose.tp1.requestFocus(true);

str = fileChoose.tp1.getText();

startPosition = str.indexOf(searchTxt.getText());

endPosition = startPosition + searchTxt.getText().length();

fileChoose.tp1.replaceSelection(replaceTxt.getText());

newEndPosition = endPosition;

}else if(fileChoose.focus == 2){

fileChoose.tp2.requestFocus(true);

str = fileChoose.tp2.getText();

startPosition = str.indexOf(searchTxt.getText());

endPosition = startPosition + searchTxt.getText().length();

fileChoose.tp2.replaceSelection(replaceTxt.getText());

newEndPosition = endPosition;

}

替换下一处

if(fileChoose.focus == 1){

fileChoose.tp1.requestFocus(true);

nextTemp = newEndPosition;

strAll = fileChoose.tp1.getText();////////////////////////////////

fileChoose.tp1.select(nextTemp, strAll.length());/////////////////////////////

nextStr = fileChoose.tp1.getSelectedText();

newStartPosition = nextStr.indexOf(searchTxt.getText()) + nextTemp;

newEndPosition = newStartPosition + searchTxt.getText().length();

fileChoose.tp1.select(newStartPosition, newEndPosition);

fileChoose.tp1.replaceSelection(replaceTxt.getText());

}else if(fileChoose.focus == 2){

fileChoose.tp2.requestFocus(true);

nextTemp = newEndPosition;

strAll = fileChoose.tp2.getText();

fileChttp://hoose.tp2.select(nextTemp,strAll.length());

nextStr = fileChoose.tp2.getSelectedText();

newStartPosition = nextStr.indexOf(searchTxt.getText()) + nextTemp;

newEndPosition =newStartPosition + searchTxt.getText().length();

fileChoose.tp2.select(newStartPosition, newEndPosition);

fileChoose.tp2.replaceSelection(replaceTxt.getText());

}
