如何检查在ArrayList中是否存在扫描仪中写入的值？

List<CurrentAccount> lista = new ArrayList<CurrentAccount>();

CurrentAccount conta1 = new CurrentAccount("Alberto Carlos", 1052);
CurrentAccount conta2 = new CurrentAccount("Pedro Fonseca", 30);
CurrentAccount conta3 = new CurrentAccount("Ricardo Vitor", 1534);
CurrentAccount conta4 = new CurrentAccount("João Lopes", 3135);

lista.add(conta1);
lista.add(conta2);
lista.add(conta3);
lista.add(conta4);

Collections.sort(lista);

System.out.printf("Bank Accounts:" + "%n");
Iterator<CurrentAccount> itr = lista.iterator();
while (itr.hasNext()) {
    CurrentAccount element = itr.next();
    System.out.printf(element + " " + "%n");
}
System.out.println();

为什么日期转换到错误的时间？

result=$(ls /path/to/file/File.*)
#/path/to/file/File.1361234760790

currentIndexTime=${result##*.}
echo "$currentIndexTime"
#1361234760790

date -d@"$currentIndexTime"
#Tue 24 Oct 45105 10:53:10 PM GMT

我有以下bash代码,它循环遍历文本文件,逐行..我试图将工作'前缀'作为前缀添加到每一行,但我得到此错误:

rob@laptop:~/Desktop$ ./appendToFile.sh stusers.txt kp
stusers.txt
kp
./appendToFile.sh: line 11: /bin/sed: Argument list too long
115000_210org@house.com,passw0rd

这是bash脚本..

#!/bin/bash

file=$1
string=$2

echo "$file"
echo "$string"

for line in `cat $file`
do
    sed -e 's/^/prefix/' $line
    echo "$line"
done < $file

我在这做错了什么？

更新:执行head on file将所有行转储到终端的一行,可能是相关的？

rob@laptop:~/Desktop$ head stusers.txt
rob@laptop:~/Desktop$ ouse.com,passw0rd

我想重新存根someHandler.getStatus,但我得到了TypeError: Attempted to wrap getStatus which is already wrapped......

it('is a test', function() {

  sandbox.stub(someHandler, 'getStatus', function(callback) {
    callback(null, {
      value: 1
    });
  });

  sandbox.stub(someOtherHandler, 'doSomething', function(callback) {
    callback(null);
  });

  sandbox.stub(someHandler, 'getStatus', function(callback) {
    callback(null, {
      value: 0
    });
  });
});

为什么导航按钮不可见？

为什么当我手动更改阵列的阿尔法值,被传递到着色器,结果是两者的相同0.0f和1.0f？

我期望根据alpha值绘制具有某种透明度的对象.

我没有使用任何纹理.我总是看到我的红色物体在黑色背景下.

glsl从java.. 访问变量

float[] color = {1.0f, 0.0f, 0.0f, 1.0f};

gl2.glGetUniformLocation(shaderProgram, "vColor");
gl2.glUniform4fv(mColorHandle, 1, color, 0);

glsl片段着色器..

#version 120

uniform vec4 vColor;

void main() {
    gl_FragColor = vColor;
    gl_FragColor.a = 0.0; // does not make object transparent
    // gl_FragColor.a = 1.0; // does not make object transparent
}

我的测试是从命令行传递的，但是我typescript使用Atom.

当我在编辑器中打开其中一个测试文件时，我在这一行看到一个错误：

expect(pageObject.name.getText()).toEqual('Some name');

这是错误：

Typescript

Error
Argument of type '"Some name"' is not assignable to parameter of type 'Expected<Promise<string>>'.at line 16 col 50

为什么这会显示在我的编辑器中？然而测试通过了。

运行量角器测试的命令：

protractor dist/protractor.config.js

我试图决定为什么我应该TSLint在我的Typescript2/ Angular2项目中使用.

暴露的规则列表TSLint:https://palantir.github.io/tslint/rules/

可用的编译器选项TypeScript:https://www.typescriptlang.org/docs/handbook/compiler-options.html

从Typescript2现在开始有一些编译器选项--noUnusedParameters,是否真的需要TSLint？是TSLint编译器选项的超集吗？

??? index.js
??? package.json

如何设置myOtherKey属性any？

打字稿错误..

Object literal's property 'children' implicitly has an 'any[]' type

对象初始化..

let myObject = {
  myKey: 'someValue',
  myOtherKey: []
};
